Some interesting thoughts as to why your first 25,000 hits are irrelevant:
Unfortunately, many entrepreneurs (and many VCs) confused one time “tryout users” with real sustainable users. As an analytics freak (I’ve invested in a number of web / Internet analytics related companies over the past 10 years, including NetGenesis, Service Metrics, and now FeedBurner), you only have to ask two more questions to know whether (a) the company really understands its traffic / user base and (b) whether they’ve got the “first 25,000 user problem.”
Naturally, whether or not you think a blog is interactive enough to be considered Web 2.0 is entirely up to you… but it is something to think about.
