After making some improvements and posting to MeFi projects, there were just 72 people playing fastr at the same time. Surprisingly enough, it's still working. The first website I saw pointing to it was Tecnicalia, a Spanish tech blog. That made me think maybe it was worthwhile making a Spanish version. I thought it would be a fun way to practice a second language, and also let Spanish speakers play in their first language. But I haven't seen anyone playing it yet.
