It's disappointing that the only login option is via Facebook, but it's cool that one can also try the service without login in at all.
Although after one adds the bookmarklet to one's bookmark bar and comes back to the site, we are caught in an endless loop of step-1-2-3 where we are indefinitely asked to add the bookmarklet again...?
Ah! No, I didn't. I since created a quote and that broke the loop; now when I reach the website I access the list of my quotes.
Sorry for the false alarm (although step 3 is maybe a little obscure?)
Facebook? Twitter? Google?
