I must must must use the preview more. I'v got too used to forums and wiki's that let me edit my stupid mistakes.
The ability to edit a digg comment for a couple of minutes is great. I'd be happy with a three minute delay on slashdot before comments become part of the site.
(Although I don't bother looking at digg much anymore, there's lots of amusing stuff but not much that actually matters to me and the comments I think are worth reading are often not the ones that get high scores).
I'v mainly posted this journal entry on the off chance anyone wants to leave me a mesage. Feel free to write comments about anything though I may delete the whole entry.
