LineBuzz insert one line of javascript code in your site and let the comment be where comments should be, the words that matters! What would be wrong with that? Everything?

1. For people who edit their blog all the time, what if they change something? how can linebuzz handle that? Lose everything.

2. What if there is buzz over lap? for example, "this is WebDevLogs", someone might want to comment on entire phrase, but someone else might want to comment on "WebDevLogs" only.

LineBuzz is not the "comment savior" if the above problems can't be solved.

Personally, I like Jack Slocum's wordpress comment system with YUI[BEWARE, THIS CRASHES YOU BROWSER] much better, it just need a better paging function so the 9000 comment page won't crash people's browser.
Seems like someone should start thinking about future's information system.
