The 25 most valuable blogs are...

As blogs have gained in prominence as sources of news and information, the value of the most popular blogs has become a subject of much talk.

Some blogs, such as The Huffington Post, have been funded to the tune of millions of dollars by investors who believe that they're the next big media companies.

But what are these blogs really worth? Since most blogs are privately-held, obtaining the data on which reasonable valuations can be performed is difficult to do.

That, of course, doesn't stop people from trying. Last year, Douglas A. McIntyre of 247 Wall Street, gave it a go and created a list of the 25 most valuable blogs based, of course, on his best guesses at valuation.

This year, he's at it again and has released his list for 2009:

1. Gawker Properties
2. Huffington Post
3. The Drudge Report
4. Perez Hilton
5. Sugar, Inc.
6. TechCrunch
7. MacRumors
8. SeekingAlpha
9. GigaOm
10. Politico
11. SmashingMagazine
12. SearchEngineLand
13. Boing Boing
14. ReadWriteWeb
15. SB Nation
16. Destructoid
17. Mashable
18. Alley Insider
19. /film (slashfilm)
20. The Superficial Network (AntiClown Media)
21. Neatorama
22. Daily Kos
23. Talking Points Memo
24. VentureBeat
25. Wowowow.com

To view the valuations McIntyre assigned to each blog, along with an explanation of the estimates behind them, be sure to check out McIntyre's full post. It makes for an interesting read.

Is Gawker really pulling in $15 CPM per page on average (inclusive of all ads on the page)? Is the Huffington Post really worth $90m?

While there are some great blogs on this list, I think McIntyre might be a little bit too generous with his estimates in this environment. What do you think?
