problem wirth google groups interface?

perhaps the owner of this list can investigate where the problem is. i wrote a report to google. perhaps they can fit it.

I consistently find that any new topic I start on google-groups rubyonrails-talk takes about 3-4 DAYS before it shows up in the list. However, any reply I do to an existing thread appears instantly on both google-groups and ruby-forum (as I'm sure this reply will as well). Do I really have to start new threads on ruby-forum and then follow up on google-groups? What gives?
