I guess the whole "like" thing was added so people can show that they agree with what the person is saying, preventing people from replying with things like "+1" or "ya this". Also likes make posters feel better and gives them more credibility (members with more likes probably make good replies and are experienced and able to help/give advice).
It looks like your post got a few likes. I can't tell if they're liking it out of irony or if they genuinely agree with you.
anyway, I like the competitive aspect of cubing and trying to break records/win events, but I definitely also enjoy meeting new people.
