"I visited - didn't know what to do." True, the only place it is really explained is here on HN, I'll fix that quickly. [edit: fixed]
"Categorize/tag them so I can browse startup-related articles (or whatever category I want)" I don't want it to become this "big", I just want to have a bookmarklet when I'm reading a good Paul Graham's article, and check if someone did a TL;DR for it already. One click.
"Auto-fill url's as people are typing." Auto-fill with what?
"If the story I'm interested in has already been summarized, take me to it." The bookmarklet does that.
"Could definitely build a mini-newspaper/ezine type of thing around this." Maybe, I'll wait to see if the website is of some interest for an interesting number of people first :)
"Don't force me to use my twitter account to do a submission - please!" I thought it was a good idea for moderation/spam protection... Maybe I should rethink that...
"Good job! Keep the iterations coming." Thanks again !
