Going back...
I should have mentioned in my blog for Thing 2 that I also set up a page for netvibes:

(I like chocolate - is it obvious??)
I thought netvibes was a much more sophisticated-looking site than iGoogle and I really like its style. I'll definitely continue exploring this after the 23 Things have come to an end.
And pageflakes:

There is a US bias with pageflakes, so I went through and changed it to UK info as much as I could. Adding things wasn't particularly obvious but I eventually worked out that you to go to Menu (iGoogle made it easy by calling this Add stuff!).
The next Thing...
I will be looking at Thing 5 tomorrow and shall blog about my experiences very soon...
