It's still basically only .com that matters. There are those few others that matter commercially (setting aside the org for nonprofits and edu and gov), such as .io, but for every 'clever domain' startup, I see 6 more who, unable to get say, frog dot com, go with something like "usefrog dot com" or "tryfrog dot com" in their early days and come back and snap up frog dot com after they get their Series C. They could have gotten say, frog dot legal or frog dot engineering but nobody wants those.
