markee174: "Judging which platform to use on the basis of personalities (and perceived views based on comments on Internet sites) seems rather bizarre as all platforms have their share of arguments and characters you might disagree with."
Yes, but many platforms have much larger communities. For example, you can happily find your niche and ignore lots of other people in the wider Linux community. Don't like the GNOME people? Hang out with the KDE people or the XFCE people or the GNUStep people instead! Or have nothing to do with any of them and find your own like-minded group.
Meanwhile in the RISC OS scene, if you don't get on with a particular goldfish in the bowl you can be sure they'll be in full view again in less than the obligatory seven seconds. And one of the platform's most serious problems is that no-one seems to have the motivation to change the water any more, either.
