I've just started reading the blog of Louis Gray, a Silicon Valley marketing and PR person who writes about being an early adopter, geek, RSS addict etc. His blog's worth subscribing to if you want to be keeping tabs on the social web technologies that crop up over Louis' back garden before they are adopted over here in the UK. Some of his current posts include blogger interaction, Twitter app Posty, trimming RSS feeds and FriendFeed tips.
Not everyone's cup of tea, but if you want to see what's coming up and if you're always looking for ways of tracking news and tapping into the important online communities, Louis' blog is worth a read. Subscribed.
