A readers asks where he can put his open problem on the web. Back in the late 80's we had three Theorynet mailing lists. Theorynt-A announced major conferences, Theorynt-B announced local workshops and Theorynt-C had everything else including various questions people put out to the community. But now we have only one Theorynt only announcing conferences and the volume of a Theorynt-C type list today would overwhelm anyone trying to read it.
We need some Web 2.0 system. A blog or wiki to post the problems. A tagging method to mark the area and status. A voting system to rank the importance of the problem. A commenting system for discussion. A sophisticated RSS system for tracking. A visual appealing and simple interface. And most importantly someone willing to put it all together for no compensation beyond the thanks of the community.
