I'm thinking of blowing out

I'm thinking of blowing out Ephemera into its own site, and I need to come up with a new domain name for it. Any ideas? Dictionary.com/ephemeron. Too complicated? Dictionary.com/palimpsest. Gothamist? Also quite similar, but smoother on the tongue? Gothamer. I also like the postmodern Gothameta and Ephemeta. Also potentials: Ephememe (ephemera + meme) and Along the same lines: Gothameme. Other sources of inspiration: Trivia Asylum - City Nicknames and
Police Glossary.
