[OSM-dev] [Talk-GB] OSM shortlinks problem

[Matt Amos]

http://trac.openstreetmap.org/changeset/16271

yeah, it was originally =, but changed to - to work with twitter.
given that the characters A-Z, a-z, 0-9, _, @, - and = have already
been used, what's the next best character? ~? +?

cheers,

matt
