How: To help us focus on bloggers we already work with, Blogads is invitation only. You need to be sponsored by a blogger in the network who vouches for you. Meanwhile, feel free to join the Blog Reader Project to get a snapshot of your readers and compare them with other blogs' readers.

Who: Blogads.com is a network of influential bloggers who collaborate to promote and sell blog advertising.

What: Advertisers order, manage and renew sponsorships (fixed-period ads) on your blog. Only ads you approve run. Blogads.com focuses on marketing and advertiser hand-holding so you can blog relentlessly.

Why: Blogads are rewarding, flexible and simple to use.

• Friendly. We love gabbing about blogs with advertisers. (Yes, we know that's weird.) We spend our days explaining blogs, prospecting, untieing knots, brainstorming with new advertisers, cross-selling old buyers to new blogs... if it helps put dollars in blogger pockets, we're on it.

• Rewarding. The average blogger makes $30 $50 a month selling Blogads, with some pulling up to more than $750 $1500 $5000 monthly. As advertiser appreciation rises, your yield should rise. Blogads receives 30% of your ad fee, unlike other networks that charge far more or won't even tell what they take.

• Networked. Allying yourself with other quality bloggers increases your revenues. As LA blogger Matt Welch says, "Network effects will work very well here. The more participating blogs from Los Angeles, the easier it is for advertisers to make a useful, targeted group buy (and therefore pay me more money!). This also works for subjects -- media, baseball analysis, DIY music, whatever."

• Flexible. You set prices, customize design and write copy to solicit advertising. You alone decide what appears on your site.
