Facebook may have gotten its start on college campuses, but the service has moved away to focus on building a generally useful product for the general public. The company got rid of features like Courses (which let you list your class course schedule) years ago in favor of letting developers build their own, for example. A few companies have been working on tools for colleges and universities, but a new competitor has gone live on Facebook’s platform: CampusBuddy.

Similar to competitors, it provides an application that can be included as a tab in a college or university’s Page, that comes with education-focused features.

The market here is still open. For whatever reason, universities have struggled to rack up fans and provide meaningful services on Facebook. According to our metrics tool PageData, the university with the largest Facebook fan base is Texas A&M, with about 174,000 fans — not a whole lot, considering that the school says annual enrollment is 48,000 students every year on its web site.

CampusBuddy has launched a free Facebook application aiming to give universities another tool to tap social networks for current students. The company already creates communities for students on its own web site, and lets users sign in with their Facebook identities; the Facebook app that launched last week essentially recreates the web site’s interface in a tab on a university’s Page. So far, our metrics tool AppData shows that the app has about 67,300 monthly active users to date, although it’s not clear how those users are distributed across Pages and the home site.

Universities like USC, UCLA, UC-Berkeley, Ohio State, Texas A&M and the University of Texas have signed up for the web site version of CampusBuddy. It allows students to set up a profile and interact with other users/students, find people in specific classes and majors, read user reviews of colleges and professors, see class and grade distributions, as well as other school data such as admissions and school statistics.

USC was the inaugural school to include CampusBuddy’s tab on its official Facebook Page, which amounts to a re-creation of the web site’s interface on the tab but allows users to search for CampusBuddy users from elementary, junior and high schools. The Facebook app includes ads for CampusBuddy’s other services, such as: paying for grade distributions, scholarship contests and buying textbooks (an external site).

Previously we wrote about another university-focused company, Inigral, which developed an education-themed app called Schools designed as a closed-system where potential or new students could get to know their universities better. Features included information and photos of clubs, groups, activities, dorms, majors, departments and lots of places for users to share information. In December, Schools had about 6,000 monthly active users and about a dozen universities had signed up.

Although universities have a lot to gain by creating a strong Facebook presence for current students and alumni, CampusBuddy’s tab provides basic interaction that its probably not useful for anyone but freshmen or people new to the school since admission, housing and fraternity/sorority stats are things acclimated students are likely to know. Features include a way for users to post questions in categories like housing or nightlife, post comments, and see what other students have registered for an account with CampusBuddy and also search majors/departments, professors and courses.

While there’s no doubt universities are scrambling for ways to make Facebook work for them — not only would it help them save money on alumni recruitment but also with fundraising — companies like CampusBuddy don’t appear to have solved that problem. There’s really nothing new with this app; it creates venues for users to add content, not any new content, but that user-generated content could be added to Facebook with the network’s current interface.

Another element is a type of game awarding users Honor Points for inviting friends, completing reviews or answering questions for “premium content,” but it isn’t promoted heavily. CampusBuddy users can use these points to:  gain recognition by attaching Honors Stars to their profiles, get “priority access” to new features and resources, be the first to see new official grade distributions before their release to everyone else, and access to “elite features” like lists of the easiest graded classes and best reviewed professors. Users can only receive points for inviting friends through the company’s web site.

In many ways CampusBuddy, like Inigral before it, have built features similar to Facebook’s own interface and not really added anything groundbreaking in terms of interactivity. Furthermore, while such programs have attracted thousands of users, the potential student-alumni pools amount to millions, many of whom have not come out in force for their alma maters on Facebook.

Another conundrum facing universities seeking to build communities on Facebook is the issue of privacy. Facebook has reset privacy control several times this year alone while universities have an interest in creating more closed communities, especially when it comes to insecure new students. Inigral’s interface was partly-public and partly-private, whereas CampusBuddy seems to be completely open, as those with no affiliation to USC can view and post information. This setup would make sense if schools were trying to build larger communities around their sports teams, the University of Texas for example has a huge football following even among people not affiliated with the institution, but CampusBuddy doesn’t state that as its goal.

As companies like CampusBuddy and Inigral continue to develop solutions for universities on Facebook it’s likely we’ll see some more configuring around Facebook’s privacy issues and more innovative ways for Facebook users to interact with the schools’ own web sites. In the interim USC’s running total of 35,000 students (not to mention alumni) is represented by 1,430 on the CampusBuddy Facebook app.

Update: CampusBuddy chief executive Mike Moradian tells us that the company has “boostrapped”its way to more than 260,000 monthly active users on Facebook by January (of a total of more than 700,000) with no outside funding.Although CampusBuddy just launched its tab feature on Facebook,Moradian tells us more products are in the works.
