Is sharing a meaningful tag, or is it too ambiguous to be useful?

If someone wants to defend it, please write a tag wiki

@Gilles LOL Maybe you make a recommendations tag to match it? #D

@Gilles Guff. If we were "all Android" here, it might make sense (as there's the built-in "Share" API, and everybody would immediately think of that). But in "general software terms": What are we talking about? Shared libraries? P2P (torrent etc.)? Share your thoughts (with other team members / publically like FB, Twitter, etc)? Shareware?

That would only make sense in combination with other terms, not as a stand-alone tag IMHO. But I might be convinced otherwise ;)
