So I’m cleaning off my bookshelf last night trying to decide which business books to jettison and which ones to keep.

I came across my copy of Jaclyn Easton’s StrikingItRich.com and wondered: Of the “23 incredibly successful Web sites you’ve probably never heard of,” how many of them are still around? After all, the book was published back in the paleozoic era of the Web (that would be 1999).

Here’s how it breaks down:

Clearly Alive: Ask the Builder, Cassette House, Coastal Tool and Supply, Discount Games, FragranceNet, Gamesville, Horsenet, iPrint, The Knot, Long Island Hot Tubs, Motorcycle Online, The Mountain Zone, Reel.com, Ridout Plastics, Tradeshop, U.S. Wings.

Evidently Dead: Expert Market, International Golf Outlet, Ken Crane’s Laserdiscs, Korea Link, Practical Online Weight Loss Clinic, Product Partners.

Evidently Bought Out: Weirton Steel.

Not too bad: 17 out of 23 still clickin’ a decade later. Somewhat ironically, though, it looks like the StrikingItRich.com URL wasn’t locked down by either the author or the publisher.

The numbers in this Mashable post suggest that perhaps it has. Maybe because people just don’t have time to tweet, since “U.S. Internet users viewed 16.8 billion online videos during April.”

Takeaway for marketers: Get offa YouTube and get back to work!

All Things Digital reports that online advertising revenues for the first quarter of 2009 are down by five percent.

(And in case you didn’t know, that headline up there is a reference to this.)

Takeaway for marketers: Keep an eye on the big picture. From 2001 to 2002, revenues declined by about 20 percent. From 2002 to 2007, they nearly quadrupled. Ask yourself: Where will they be five years from now, in 2014?

I like Morning Joe on MSNBC, though I do think Joe needs to quiet down and let Mika speak up more. Or maybe Mika needs to be more aggressive. And what were those shoes she was wearing last week, anyway?

Anyway … seems like Morning Joe’s Starbucks sponsorship is stirring the waters. Check out what AdAge, the New York Times, Time, MediaWeek and The Daily Kos have to say about it all.
