"Thanks for your comment, Daniel. I concur with much of your experience on Tsu. To their credit, they have taken some pretty dramatic advances against spam since last week, and it is now possible to report both posts and profiles. However, you raise a larger concern that I share. Right now Tsu seems like a network without a purpose (other than trying to generate enough views and get enough signups to make some money). And it lacks a lot of the sophisticated filters and options (such as groups) that mature networks like Facebook and Google+ have. Right now my Tsu stream looks like I'm just hitting some "random - show next" button at Reddit ;-)" - Mark Traphagen
