I recently go the following email that may be an answer:
I am writing you in (very belated) response to a post on your blog in mid March. You posted a message called "A Place for Open Problems" where you suggest: "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."I corrected them about Lance making that posting, not me. Of much more importance - they have a wiki!! Is it good to use? Will we use it? This is one of those chicken-and-egg problems where if enough people use it then it will be a good resource. Of course, Matt and Robert are not innocent bystanders- if it has a good interface and other features then we are more likely to use it. It seems to be open problems in all of mathematics, though computer science theory is a category. If there was a wiki tailored to Theory would that be better or worse? I would guess worse because the distinction can be artificial anyway.
Together with Robert Samal, we have just finished the construction of a system which matches your request quite closely. There are still some small modifications we are making, but it is alive and fully functional, and we would greatly appreciate any input/publicity from you and your readers. Our website is called "The Open Problem Garden" and lives at the following url: here it is
Hope you enjoy it.
Best, Matt DeVos
And of course there is the issue of- are you better off working on your open problems or posting them? It may come down to this:
Which is greater, your curiosity or your ego?
