There's no need for you to feel gutted, Wrighty; the post wasn't locked because of something you did. Sometimes, when threads go too far off on a tangent or wires become crossed between posters etc the mods feel the need to lock the thread down to prevent the situation becoming worse or arguments from escalating.
I congratulate you on your ongoing recovery from your illness and would suggest that you have it sussed - a day out at the shoreline will cure most things, I reckon! There is no need for taking something like this to heart as none of it, in my opinion, reflects badly on you. It was simply a case of two very different people looking for two very different things from their fishing and, at the end of the day, this diversity is one of the great things about what we do - if you want to hunt monster conger or specimen bass then good luck to you because, without people like this, we wouldn't get to see quite so many of those amazing fish we all like to read and dream about. On the other hand, if you want to bash the tiddlers (something I also enjoy doing from time to time) then kick back and enjoy it - world championships have been decided by bags of smaller fish than yours.
I don't think there can ever be a general concensus on what constitutes a "good" or "successful" session. I really do understand and sympathise with Chris Grace's frustration at the fact that we're often forced to fish for small fish. Sad? Damn right. Frustrating? God, yes. But if, on occasions, that's all there is then that's all we can fish for and we must make the best of it. So just keep doing what you're doing and, most importantly, keep enjoying it, whether you're after fish of five pounds or five ounces.
Good luck to you all and tight lines,
