@Nero The "too minor" rule was always a mess. Don't worry about that. Worry about fixing the post. Some posts only need a few typos fixed, and if that's the case, go for it. If you think they need more than that, then do more. That's the theory, at least. It doesn't play out quite as well on
Stack Overflow, just because it's a bigger community with more, let's say "inertia," but here on Startups, I'm sure your edits will be appreciated as long as they fix everything you feel needs fixing.
