You'll have to forgive another navel-gazing fluff post, but I thought this was interesting: I happened to read two separate blog postings today that mentioned Seaside even though they were mainly talking about web frameworks in other languages. One was from Ian Bicking, talking about Rails and Python; another was from Dion Almaer, surveying Java frameworks. I flatter myself that this is evidence that Seaside (along with related frameworks like Wee) is slowly moving from being simply a wacky out-of-the-mainstream way of building web apps to being the canonical wacky out-of-the-mainstream way of building web apps. Here's Ian:
Rails ... doesn't have any novel ideas. I'm not trying to talk it down, that's just the reality of what Rails is -- it's not Seaside or Wee (and if it was it wouldn't be so popular anyway).
