Came across Howard Rheingold’s Scoop.it page recently. Lots of interesting stuff including a couple of Twitter tips – how to create RSS feeds from twitter lists (easy), and how to get an RSS from a Twitter search using Topsy, now that Twitter has removed RSS.
I recently switched my Delicious bookmarks over to Google Bookmarks. Mainly because it’s one less login to remember, but it looks like Goolge does a pretty good job with bookmarks too. Very similar features to Delicious, although my initial reaction was that the community is not as visible as it is in Delicious.
