I posted my thousandth link today to the social bookmarking service del.icio.us.
The link itself was Sky & Telescope Interactive Sky Chart which I spotted in Chris Heathcote's links. It caught my attention after the amazing lunar eclipse last night (my blurry photos of the eclipse really didn't do it justice).
To give an idea of the sort of links I bookmark over at del.icio.us, of the 1,000 links over half are tagged with 'geo' (something related to geography), just over 15% tagged with 'drupal' and 7% tagged with 'opensource'. The top 10 are mostly geo-related:
You can view all my public links at del.icio.us/dankarran to see what I've been reading recently (or have saved to remind me to read it later at my leisure).
