The museum blog of the 21st century? For anyone wondering:
Twitter is a free social networking and micro-blogging service that allows users to send “updates” (or “tweets”; text-based posts, up to 140 characters long) to the Twitter web site, via the Twitter web site, short message service (SMS), instant messaging, or a third-party application such as Twitterrific or Facebook.
Updates are displayed on the user’s profile page and instantly delivered to other users who have signed up to receive them.
