I'll throw my hat in the ring... I'd like to attend the Wolfram Technology Conference and would like to be sponsored (I cannot attend otherwise). I'm a student in the U.S., and would like to attend 17—19th of Oct (i.e., only the conference and not the pre/post events).
I'm fairly active on the site and participate regularly in both, answering questions, and community moderation. This conference is probably the most relevant to the Mathematica community and it would be a good opportunity to get some new users (most of them possibly at the intermediate to expert level). I believe I can do a good job at explaining what this site is about, who it is for, the policies, community aspect, moderation, chat, etc. and especially about where it stands wrt the alternative that everyone's familiar with — MathGroup. It would also be great to meet in person some of the regulars here whom I only know via SE.
I can also blog about the conference and the sessions at our blog, summing up my experiences (one for each day of the conference would be a good number), perhaps even live tweet certain events and happenings from the @stackmma twitter account (maybe will have to work an arrangement with the team, since control over this account is not typically handed to users/mods/community).
Thanks to everyone that supported my application for sponsorship to attend the conference. SE was very generous and agreed to fully cover the costs of registration, accommodation and per diem for the duration of stay. Unfortunately, the cost of the airfare (which was not being covered), was more than what I can afford to spend as a student at this point in time. I would've grabbed SE's offer in an instant had the situation been different, but for now, I've decided to withdraw my application so that other active members of the community can be sponsored. I strongly support Yves' application and also highly encourage others to apply!
