As7ab which means Friends in Arabic is one of first Arabic social networks owned now by Yahoo! Maktoob, the social network was launched around 2 years ago by Maktoob, since then it has been adding features gradually.
The new features As7ab has added is alerting users of people who work at the same company or study at the same school.
I could not find this on the main As7ab website, but I found about this via an email alert from As7ab telling me that Maktoob has lately added search capability to the site that would provide you with information about friends that you have something in common like workplace and school it also alerted me that there is one coworker at ArabCrunch.
As7ab maktoob has many features such as messaging, ta7di (challenge) like who is hot app on facebook but instead of who is hot, it has things like who is smarter and so on. other features include: celebrities were users can follow celebrities news, events, photos,, networks, free gifts app.
As7ab Maktoob competes with facebook which launched its Arabic Interface back in February 2009.
Looking at what the mother company Yahoo has done in the consumer social networking area, As7ab Maktoob looks better in terms of features, but needs some tweaking and opening their APIs, not to mention a portal wide integration.
