I might be in a minority of one, but I find Twitter very useful to find out:
what is on at the local theatre;
what the Ramblers Association is up to;
to keep an eye on Chorley FC's away matches - they have a live Twitter feed from the match;
what events are being held at the library;
what my walking companions have planned;
what bands are playing at the several pubs in Chorley with live music at weekends;
what the local councillors are up to, although whether it is truth, propaganda or lies they post is open to debate.
All in one place. Very useful if you are picky about who you follow.
