It would be good to have a possibility to get a short version of a permalink to content by clicking something for example.
The reason is quite simple. In all foreign languages, that don't use latin alphabet, current permalink format looks very disgusting to the eye:
It is very long, very unclear and boring. It is not good for insterting into emails, sending by IM and all other purposes. Long version is good mostly for search engines. For humans it is very inconvenient most of the time.
May be even post permalinks could be short by default since they don't have much value for search engines.
