Google is the new Microsoft in terms of ignoring anything outside its own monoculture. I gave up on Chrome some time back. I tend to use Firefox at the moment, with Chromium as a reluctant last resort if something really doesn't like Firefox. I still remember stuff that only works on IE and MS systems (and sends email notifications that use ancient encryption methods that modern SMTP doesn't support by default). Sadly I still have some of that in the house because I haven't gotten around to upgrading it.
As for checking against latest browser releases, that's a fool's game. I tend to hand-write boring HTML with an occasional bit of CSS and rarely some Javascript, and if that doesn't work on your browser then I guess you're not going to look at my page. I check it out when I write it to make sure I haven't done anything too stupid, but then it just sits there taking up space on the web.
