Fred Wilson suggests:”Most people still think of Typepad and Moveable Type as blogging platforms. But I think they are the future of websites.”
Jeff Jarvis adds in a comment:
I think it’s half the platform. The other is RSS. In the job I left yesterday, one of my undone projects was to convert the architecture of local news sites entirely to RSS: Everything is a feed. So a home page is a feed of latest and biggest stories. A town page is a feed of newspaper headlines, blog headlines, classified ads with the latest listings in the town, forum thread headlines, weather, and so on. Looked at that way, there are two kinds of content in the world: reference (fed by wiki) and feed (rss, fed by blog software).
Then the overarching thing one needs is an architecture for finding things. That was navigation and taxonomy. It may — emphasize may — shift to search and tags.
Michael Parekh also has a commentary.
