I suspected that there was already a PR where what I'm suggesting was discussed. :-)

Now you've learned more about the people who are interested and the words/terms they use, you are more in a position to make that decision now. So, in some sense it was good to wait.

However, I think that if your growth has been relatively flat and you have evidence of other platforms clicking with consumers in a big way, then it may actually be time to think bigger than incremental improvements on what you're doing now.

One thing you could do is run a set of ads with 10-20 different names along with a catchphrase like:

    Gittip
    An economy of gratitude, generosity, and love

- or -

    NameIdea
    An economy of gratitude, generosity, and love

And then see how well you perform. It would be a fairly affordable way to determine if you have a problem or not.
