I hit on the that name out of desperation leading to silliness. The idea has to do with directed acyclic graphs of trust relationships, hence trees, hence "grove".
There aren't a lot of real-world analogs, so I'd been struggling to find some short name that explained the concept. I was working with a few others until recently and they had picked names like "layervote" which I never liked much. "Grovr" is obscure, but it makes me happy, and I'll probably make trees the fundamental graphic theme and metaphor.
But now you're telling me that misspellings are actually a big problem? How much of a problem, quantitatively?
Does that outweigh googlability? (On the other hand, if you add one letter, there is a popular children's TV character there which I'll never outrank, so that might be a problem.)
