Update:
Per comments I've added Kathy Sierra in the "established" list and Dan Brown in "up and coming".
E-consultancy recently came up with a list of top user experience professionals as ranked by general awareness and reputation. Interesting to see that Seth Godin came up on the list as well—though I feel he's more in the marketing camp in comparison to the others. The names are:
1) Jakob Nielsen
2) Steve Krug
3) Jared Spool
4) Donald Norman
5) Jeffrey Veen
6) Jesse James Garrett
7) Louis Rosenfeld
8) Jenifer Tidwell
9) Seth Godin
10) Eisenberg brothers
So let's have a little fun. I've re-created the list and swapped out Seth and the Eisenberg brothers (an editorial modification). I also added a second list with some names that aren't as recognizable, but are making an impact in the profession (including yours truly—hey, it's my blog ;). In the "democratized" Web—how do you see it? Voting on the ones you feel strongly about will probably move them up on the list. Not selecting will have the opposite effect. You can also add names manually if you don't see someone who you think should be on the list. I'll give this some time and post the results when activity dies down.
I don't know where this will go—but what the heck?
