I like the way medium.com deals with IDs, 10 random hex chars (i.e. > 10^12) put at the end of the slug are more than enough for most use cases that can be addressed via a url and still clean for search engines and humans. But also the way letterboxd and also quora deal with URLs is admirable but it needs special care (at least in the case of quora)
