We are all very excited about DrupalCon coming to London (well London-ish - http://london2011.drupal.org/conference/venue ) - and now that we are Silver sponsors we are literally jumping for joy ... now we just need to think of something to put on our very own exhibitor table ...
Not strictly a Drupal post this, but something that I was playing with yesterday that I was really struggling to find any documentation on.

The basic approach is you are providing a link to http://www.facebook.com/sharer.php?s=100 which is the basic share page (typically this is shown in a popup).
