My only concern is that such a generic term negatively affects findability. E.g., it makes brand monitoring or web-searching very hard. You won't rise above the noise.
You could address the findability problem by adding a unique token to the name (e.g., 'Experiment42').
You need to tell people that you use Experiment the Crowdsourcing Website, not experiment with crowdsourcing or use your experiment to crowdsource funds. And the same for googling.
(And BTW I really liked Microryza; I do know that it may be hard to spell (still easier than mycorrhizae), but Ryza sounds nice too!)
And an anecdote: when I was mailing with Cindy Woo almost a year ago, I joked about the tagline:
"
Mic[r]oryza
Mycorrhizae spelled in the sane way
"
I am definitely visiting this place, when the next time in SF!
