It would be nice to be able to filter people based on some sort of tag. For example, I'm interested in learning programming in Python, but not programming in Lisp right now. For Design, I guess this might involve the tools they use? Photoshop, InDesign, etc. (This might be a gibberish example - I'm not a designer.) It took me a little bit to figure out that I could see the bios of other people by hovering over their name. It might be beneficial to add a default tooltip to those without something entered... something like "This user has a blank bio." It would also be good to provide a hint that that hover information is there - I did not expect it and only found it by accident.
