Ehm, ... No - thank you for asking :)
I'm not such a big fan of the wp.org profile pages and accounts. I fix or extend sometimes stuff at the codex, assign to a trac ticket or even sometimes publish a mini-plugin (that i not maintain then), but I really don't care about wp.org profiles.
But - as you're already asking - i'd be highly interested in having more than just one "website" field. Currently I'm linking to my github account where people can grab free open source stuff. Adding my upcoming page and maybe some project pages over there would be really nice. Best if i could name the label myself or choose from a category like "Website: work", "Website: personal", "Website: open source", etc.
