Via Bloglines I discovered Multiply. This combines blogging with social networking. You have 1GB of storage to store photos and articles that can be viewed either by everyone or by your circle of friends, colleagues etc. I've put a few bits up there and am waiting for someone to join my contacts. My page is here.
I like having this site to play with stuff like semantic web, but the other options allow quicker posting. I shall try to bring them together somehow. Bloglines has an RSS feed that I should be able to add to this site. Just need to work out how.
