I signed up for a Twitter account, and maybe I should have been more anonymous than I was (didn’t occur to me), as already I have had people trying to sign up. The fact of the matter is that I wasn’t intending to use it to tweet, as such. The reason I opened the account is that my Kindle has the ability to share my book-reading habits with either Twitter or Facebook. So by connecting it to a Twitter account, I can then pipe the resulting messages through to WordPress, and then LiveJournal.
So the Twitter account hasn’t got anything of interest on it, other than “Test” messages, and remains protected. Once I get the Kindle link to WordPress/LJ working, I may consider enabling traffic the other way – so that new blog posts get tweeted – but I don’t actually need another social network/time drain at the moment!
