Not sure how configurable this is, but would it be possible to have less ridiculous URLs? An idea might be to take the hash (it looks like you're using some sort of hash?) and then encode it base-36 like reddit, or even, (for a bit of individuality and human memorability) take a list of some number of words (preferably large) and encode it in that base where the digits are the words, e.g base-3 with 0 = telescope, 1 = dog, 2 = house, and so 3 = DogTelescope, 5 = (3+2) = DogHouse, 7 = (2*3+1) = HouseDog etc.
Oh wow, I did not know that. Well I'm sold, thanks for replying. Meteor looks to be a pretty promising way to build realtime applications, I see what all of the fuss is about now.
Meteor does have the spiderable package (http://meteor.com/blog/2012/08/09/search-engine-optimization) which means that URLs such as http://demo.telesc.pe/posts/08d0105f-0a1c-43a1-b11a-5ba8875e... will be indexed by google.
(Actually they won't because we haven't enabled spiderable in this deployment of Telescope, but it would be a one-line change to do so).
