To be honest I do also stir the pot a little - a very little, sometimes - but in general I do visit forums because I like sharing what I have in common with others, for example a passion for cycling or particular bikes, and not to what me and others do not have in common or what us divides.
- I show people my stuff, I tell them what I like, I tell them I do like their stuff (if I do) and so on.
- I avoid what I do consider not interesting or dislike. On rare occassions I speak out however, but it is minimal as I don't bother.
