Excite announced this morning that they are outsourcing all their incoming email functions to BlueTie. This means that the Excite FBL and whitelist are being discontinued with no plans for replacement.
Over at Deliverabity.com, Dennis is accepting feedback from senders to forward on to Excite.
Edit: I am going to close comments on this post. This is not the place for Excite endusers to comment on the new changes in the interface.
