Hello everybody,
Just like you I wanted to try this new potentially cool service, and indeed it took a awful lot of time (a few days) before I received a message from twitter that yfd was following me back.
I wonder what takes so long... this is really the most terrible way I can think of to welcome potential new users. However, once the service is up and running, I must say it looks awesome, and I think there is a lot of potential here.
So my advice would be to exercise your patience, if your are looking for a better alternative to daytum, I think you won't be disappointed.
Would be great if this turn into a open source project.
F.
