I long since gave up banging my head against the wall of Web 2.0’s solipsism. My argument has always been that Web 2.0 AJAX developers don’t think about the needs of AVERAGE PEOPLE.

Now Josh Kopelman has sharpened the argument:

Too many companies are targeting an audience of 53,651. That’s how many people subscribe to Michael Arrington’s TechCrunch blog feed.

Web 2.0 entrepreneurs who read TechCrunch daily (and who power-use multiple sites with “tagging” and who subscribe to 100+ tech RSS feeds) need to occasionally turn off the PC, put on some clothes, and head down to the local Walmart to spend some time hanging out with the mainstream.

Too many Web 2.0 start-ups — nothwistanding the success of MySpace, Flickr and a few other mainstream apps — are living in a bubble.
