Business 2.0 is running an interesting article called The Next Net 25 in which 25 newish companies are identified as the potential next Googles, Amazons, and Microsofts. To regular readers there's nothing too suprising in any of the five categories: Social Media, Mashups and Filters, The New Phone (VoIP), The Webtop (web-based office), and Under the Hood. Digg and YouTube are the big names in Social Media, 37signals shows up in The Webtop, and so on, but there may be a few companies you haven't heard of, like Jigsaw in the Under the Hood category, which lets salespeople exchange company managers' contact info. Overall the list is very Web 2.0 and worth a look if you want a peek at who might be among he big players in a year or two.
