Mena Trott (Six Apart): "We're launching a solution for TypePad next week to inline RSS (i.e., subscrbe to RSS Feeds from your Blog) that won't require playing with script."
It seems that everyone is following on now. FeedBurner launched its BuzzBoost feature a couple of weeks ago, and now it seems TypePad is going to offer the same thing. WordPress has had similar functionality with a plugin for at least six months now. RSS Digest launched doing the same thing, though in a more advanced way, than any of these offerings, in mid 2004.
Thankfully FeedDigest has kicked everything up another notch, but perhaps we'll see more advanced digest features from everyone else in a year or so. It's going to be fun!
