Try not to listen to the advice you get on this board too much - Kids and scammers - and people that guess or listen to other kids or scammers instead of actullay studying what the engines do. There are a couple of guys that know somewhat what they are talking about, but for the great majority ........
If your blog is on Google blogs -don't bother they spider it. Don't have high hopes of the other engines giving you good listings.
Many people rushed to throw up a blog as soon as they found out that Google engine was were giving a bit more preference to blogs (because of the popularity Google rushed in to be one of the first engines to try to increase their market share by showing the public what they thought they wanted ). Google also jumped into the blog business to try to take advantage of the blog fad. That preference soon faded out as blackhatters (Search engine optimizers who try to trick the engines) began throwing up useless blogs for the sole purpose of increasing standings). Google doesn't like being tricked and put an end to it.
So here's the deal, If you have a
good blog or have something to say, get your own domain and a blogging script. If it is search engine friendly (which by the way is a silly term simply meaning that it allows SEPARATE Meta tags for each page instead of using the same metas in a header file for all pages and a well written code that doesn't throw out numbers and letters a half mile long in the url box ...lol)
So why are separate meta tags important? Here is a image of Google spider spidering the home page of a site. I hadn't put in the meta tag mod for the cart yet (a mod that allowed separate meta tags) 0.00% means the spider did not eat it, (notice the first page of the cart was gobbled up - then it choked on the rest) -

I wanted to prove the need of the purchase of the mod to the
Pro Bono client so I showed them - clients like pictures....lol
The next time the spider came thru it indexed the cart - I could see it do it.
So to answer your question, if it is a Google Blog - it's already spidered and not much chance of doing very well in the other engines unless you made it very unique and very good content - it's not yahoo's and MSN's job to give Google business.
If it's on it's own domain more than likely MSN, Yahoo, and google have found it......
Just to make sure submit it to the engines, don't bother using a service or a submission program they just want your email address to add it to a spam list. 99.9% of the other directories, link farms, etc is a waste of time.
