"As on Facebook though, not liking something generally means people don't like it. Same on Mudcat - I often put up a link thread here to something I've done and if no one comments it's because they don't like it."

Oh Mr Blandiver, that's so not true mate.

There are all sorts of reasons why people don't "like" a link that people have put up on Facebook or on here.

1/ They've already "liked" 3 things you've put up this week
2/ They don't see it
3/ You haven't reciprocated when they've put something up
4/ They don't want you to think you're too popular (some of us are English after all!)
5/ They don't know you and they only "like" their mates stuff
6/ You're better than they are
7/ They've already "liked" a dozen other peoples stuff today
8/ They don't read anything anyone else puts up anywhere anyway and are only interested in their own posts.
9/ They just can't be arsed.

If you read no feedback (online anyway) as a negative I think you're misreading people.

I think JohnCharles's checklist above is a much more accurate way of judging if people like what you do.....
