Today I made the change to Blogger in Beta (see here). The only noticeable change so far is the nice little "label" feature that enables you to categorise your posts. There may be some more goodies in store, but that's it for now.
I'm just glad to have my PC back in working order after more than a week of nasty hard drive grief. PC World "We're with you every step of the way!" weren't exactly helpful. Unless being kept on hold for long periods on an 0870 number without actually getting to speak to anyone is helpful. A local chap sorted the problem out and managed to recover most of my data.
