1. Abigail Harrison: Hashtags: do people really use them to discover? Hands-up people.... maybe social media people do and 'normal' people don't? #twittersci

    .abigailH hashtag discovery usage is low because of Twitters anaemic implementation. See Diaspora for a great, well-used implementation.

  2. If you’re taking your website down for maintenance, for goodness sake leave both the takedown date and the estimated date it’ll be back, or there’s no chance anyone’ll “check back soon for updates!!!”

  3. Finished reading The Silent World by Jacques Cousteau.

    It’s a bit strange in that it has no real order and is a collection of semi–related stories about the development and use of the aqualung. Very informative about some of the physiological effects of diving.

    A particularly potent part is Cousteau’s story of the first time bottom trawling had ever been filmed, revealing it to be a hideously inefficient and ineffective method of trawling. No–one had ever realised before, because no one had ever actually seen a net working.
