Too high. > Ignoring cross posts, for a 13 character hash: > > 1. Effectively 0% > 2. Effectively 0% Way too low because of "7 plus/minus 2". As a strawman suggestion, I'd say that once you get down to 5% and 0.1% respectively, you're done because in many contexts cross-posts will bring you up by a similar order of magnitude anyway. For five-character hash, I get 13% and 0% and for six, 0.4% and 0%. I think 1 in 8 messages is probably more than I want to ask users for an extra click, especially if cross-posts are kicking in substantially too. So six looks to be the sweet spot. So I'm convinced that a shorter hash makes a lot of sense.
