To date MyBlogLog clocks in at about 50,000 users, fairly impressive considering the fact that it launched in Mar 2005. And with the recent acquisition by Yahoo! it looks set to grow from strength-to-strength (Especially with a 2% daily growth rate).

From my personal observation, MyBlogLog users tend to be fairly active, especially since the service combines the best features of blogging and social community sites.

As Scott observes, the MyBlogLog widget (typically displayed in the right sidebar of most blogs) certainly proved to be its secret weapon.With blogs already being very social-oriented, the widget only helped accelerate the pace of the service’s “virality”.

It’ll be interesting to see where MyBlogLog fits into Yahoo! strategy.

Niching themselves in the blog community space certainly makes sense for MyBlogLog, especially against a behemoth like Google.

Though Google owns Blogger and runs it’s Blog Search service, it doesn’t have a strong suite of blogging-specific analytics or value-added suite yet.

Here’s where Yahoo! and Microsoft’s Live search services can stake out and lay their stakes on new areas.

With Google already claiming mindshare for text and graphic-related search, the other search engines can focus on other areas like Yahoo! Podcasts and Microsoft’s Miss Dewey search engine.

For more details:

• Lee’s interview with Scott Rafer

• It’s highly targeted
• It’s immediate
• It’s low cost and often free

The downside is because of it’s interactive nature (which contributes to it’s virality), spam marketers will always try to flood you, and drown out your message with their spam.

This includes, but is not limited to:

• Posting irrelevant images (usually a scantily-clad female) in their avatars [see: How Your Social Network Avatar Can Make Or Break Your Internet Marketing Efforts]
• Comment spam: “I like your site, come visit me at (website address)”
• Being generally obnoxious (use rules of social etiquette to figure this one out)

On social community sites like MyBlogLog, Eric and his team have instituted several measure like: limiting personal messages to 20 a day (with an innovative reciprocal message feature in place) , and eliminating animated GIF avatars in favor of single (static) image ones.

But that still doesn’t quite solve the problem of ‘widget spam’ where people with link baiting avatars feature on your sidebar widget that appears on the right of this blog.

Fortunately, MyBlogLog community manager Robyn Tippins informed me that MyBlogLog includes features to block both visitors to your site, and mask your presence on a sidebar widget with the ‘cloak of invisibility’ feature (the name I’ve given to it).

Initially I had asked Robyn about killing the community visitors altogether. (which might seem extreme, until you consider that it creates a better user experience for your visitors)

Robyn responded:

If it’s on the [sidebar] widget you can hover over then and click the red x.

At this point there’s no way to kill visitors to your community page (but you can kill community members, I think).

I’m annoyed too by those avs. We are killing animated gifs this week, but the sexy graphics are a pet peeve of mine too (and I’m hard to offend).

Here’s how you’d delete visitors (say if I wanted to remove my buddy Ryan Chua permanently from my sidebar widget:

And similarly if I wanted to ‘mask’ my presence on another blog:

Let me clear the air, I am personally not offended by these images, but if they affect the blog readers user experience, I will step in and moderate the blog.

I’ve gone one step further and made the recommendation that MyBlogLog could include a classification system that is moderated from a central node at MyBlogLog. Avatars could be flagged with a “G” or “R” rating like movies are. Or maybe it’d be easier to setup a NSFW (not suitable for work) rating (I’ve been told nude images have been used for some avatars).

True, it would reduce some traffic in the short term, but when you look at how this increases the longevity of the social networks (some of which have degenerated more into ‘spam networks’), it also makes the network a more legitimate and credible medium in the long term.
