Just before Christmas last year, we took a trip around the web - and around some of the Guardian's writers - to find out what sites they recommended. The result was our list of the 100 most useful sites.
Well, now it's six months later - that's about approximately a squillion years on the internet - and we're looking to update and refresh the list to keep it up to date.
And we're asking for your help. Leave a comment with your recommendations (while self-promotion is expected, it's not really desired).
