One type of company largely uncovered in the web 2.0 blogosphere is the emergence of vertical marketplaces – or at least the framing of them that way. Of course, eBay has traditionally been the ultimate marketplace brining buyers and sellers together. And certainly the general online classifieds (like Craigslist), job boards (like Monster), and dating sites (like Match.com) have flourished since the dawn of the internet of “Web 1.0.” But I am beginning to see a set of additional verticals emerging outside these established forums, and it will be interesting to watch how they progress.
There are times when a general classified ad would do, but when a vertically focused connection service will better facilitate a transaction between interested parties. That is, as long as the market is liquid.
