My sidebars are out of control. At the last count I had the following:
Reading: a CiteULike link (papers I'm reading or have read)
LibraryThing which provides a random feed from my collection (cataloguing just started, so only 122 so far)
On my Bookshelf, a TypeList of things I'm reading right now, mostly library books
Music: Audioscrobbler, which links to my Audioscrobbler profile (shows what I've been playing in iTunes and the iPod)
Photos: at the moment I have two links to my Flickr photos, one to the whole library and one that shows the most recent ones. This needs trimming. I also have TypePad photo albums and some .Mac ones as well, but Flickr is where current material goes.
Then there's the archive links, the RSS feed etc etc. So I've just done a quick rationalisation. I hope it makes things clearer.
