I was a massive of fan of Dave's until I started following him in Twitter where I guess his 'real' self comes out more. He's a bit of an arse tbh 
Shame.
I follow him on Twitter, and can't think of anything much he's ever tweeted that's come across as arsey. Do you have any examples of things he's said?
I'm nailing my colours firmly to the mast of of the' I really like Dave' flag, and in fact if push came to shove I think I would name him as my favourite current member of the team (with Will being my ultimate favourite). I've never been keen on the girls on the show apart from Lizzie, Dom is lovely but just doesn't register as a favourite with me for some reason, Chris irritates me a lot sometimes, and I've really gone off Aled over the years as his ego and fake stupidity have got more and more out of control.
But Dave has always been way up there in my affections over all the years I've been listening, and contrary to what a lot of people on here have said recently, I honestly haven't noticed him changing and becoming less funny, more miserable etc. lately at all. I'm really puzzled as to where those opinions could have come from, so if anyone could enlighten me a bit then that would be great!
