igoogle

The first part of the 23 things program was to create an igoogle account.
This is something which I've been using for a while as my homepage in my browser.

I think its great, mine is pretty simple but its got the main things that I use a lot:
Google calendar
Google search bar
My gmail account
My hotmail account
Wikipedia (always need to know who was in what band, and how old whatsit off the telly is)

The other bits I don't use as much, but they're handy to have.

Oh, and my current theme is a fake Banksy. Mostly as it's fairly unnoticable.

Generally I'd say that customised start pages are pretty good, as they're tailored to what you want/need, not what someone else thinks. They're especially useful if you use a number of computers, as you don't need to rely on browser bookmarks.

The main downside? You miss the intersting facts and interpretations of the Google homepage. Can't have it all I guess.
