Thing 3 is the creation of a blog. I have always wondered how people find the time to blog. The chance to have a go is welcome, and I hope eventually that I might turn this into a regular blog for our departmental homepage.
It's easier than I thought it would be to set up something basic, and posting, editing, etc. seem to be fairly intuitive.
Alexandria seemed like an appropriate name, though I might change it to "Lost in Alexandria".
So far, "23 Things" has been well set out and informative, and I am looking forward to exploring more of the Web 2.0 environment beyond. There is life beyond Facebook!
