Is he "famous" for no reason? He speaks at web 2.0 conferences, there are stories about him on news.yc all the time... (Yes, I'm using the word "famous" liberally.) Why? What has he done exactly?
Here's what I've got. Feel free to add more. He:
a) worked on rss 1.0 when he was 13. woopty-doo
b) there was the Infogami - Reddit merger, which made the AOL - Time Warner merger look like a genius move for Time Warner in comparison. it is often said that aaron added no value after the merger, while taking a huge chunk of reddit's stock in the process. There's a lot more to this story, but I won't go into the details.
c) started a half-dozen half-baked startups. (I'm using the word "startup" liberally here).
d) has a blog
What am I missing? Can we stop up-voting every story that even mentions the guy now?
