I used uber for the first time this past Friday and was very pleased. Some facebook friends provided essential info that affected my decision to do so.
Some of the Uber discussions - they seem to be housed in various locations:

I did not do a search for lyft and other services, but I know it would've been useful to have a one-stop FT resource last Friday; I typically use public transportation but it was not feasible for my last trip. It could also be useful to other FTers, be it the uber (and similar service) veterans or newbs like me!
