Since I do frequent the 1x1 section more than the groups, I generally have a liking for more detailed interest checks that also tell me a little something about my partner and what they're looking for from me. It's a fast and easy way to judge whether or not it's worth the effort of answering them. I may be a little picky though. I like seeing expectations and limits and plot ideas up front, then I can respond with my own back right off the bat. Streamlines the process, for me anyway. There are some that I admittedly think might be going overboard with the sharing, but if they're comfortable telling the board those things, then there's no reason for them not to, I suppose. 

On the other note, I do think a place where everyone can advertise their interests or quickly check up on other players and 'shopping' around if a group needs more writers or some such could be a great idea, if people post there. There is an old thread HeySeuss put up [url=http://www.roleplayerguild.com/topics/10615-roleplayer-profile/ooc]here[/url] that kind of matches the idea, though it could probably do with being updated and put in a more visible position.
