This is not BS. It's free, so definitely worth the little bit of effort. Angela will send you other sources of high PR links too.

After about a week with the system I am very impressed. I suspect there will be many more reasons to like Docs, but here are the first three...

1. Sharing documents is very easy. Just add someone else's Google login email address and it is done. You can optionally send an email to your collaborators telling them the file is shared.

2. Folder organization works nicely. You can save your text documents in your own folders, then share them with others who can then organize them as they see fit. This accommodates people who have a difficult time with file and folder organization. Believe it or not, everybody does not like the abstract file and folder model used and taken for granted by computer geeks everywhere. With Google Docs you share the specific document, not the document-in-a-particular-location, so Collaborator B does not have to buy into Collaborator A's folder structure.

3. The default formatting used in the basic text "documents" translates nicely into most article submission and blog entry forms. MS Word notoriously adds characters that article and blog entry forms do not like.

Both of these factors should make it worth the effort to try to get your content on high PR sites. But the question is "How"?

One very useful approach is to leave comments or feedbak on interactive sites such as blogs or social networking sites. These links will usually be in the form of comments left in response to posts, stories, videos, etc.

Unless you are happy just leaving meaningless spam comments, leaving legitimate (or even semi-legitimate) comments on blogs takes time and effort. You have to actually go to the blog, read the posts, do a little bit of thinking, and then write a comment.

I don't know what the average time would be for doing this, but I'm pretty sure if you were to try to create an efficient "system" for commenting, it would be difficult to get the process down to less than 5 minutes per comment.

Yes, I know there is software that will find blogs, isolate posts according to keywords, and then let you create comments right from within the software shell. I've looked at this sort of thing and have not been convinced it would make the actual commenting time shorter.

The three most important criteria (from the "link value" perspective) for taking the time to create comments (either manually or semi-automatically) are:

1. The "authority" of the blog (measured in Page Rank)
2. The "relevance" of the blog to your own niche, and
3. The "do follow" or "no follow" status of comment links

I have already briefly commented on the "authority" question. I know that PR is not the be all and end all when it comes to ranking in the SERPs (results pages), but it does indicate potential link value, at least in my experience.

From the perspective of link value "relevance" is probably not as important as most people think. See my previous link relevancy post for more on this. But from the "I-actually-know-what-I'm-talking-about" point of view it makes quite a bit of difference. If you're taking the time to read the posts you're commenting on, you might as well read something you're interested in and are likely to learn something from. You will also be able to create comments more quickly because you'll have something intelligent to say.

On the "do follow" question, you have to know a bit of history to understand the significance of this. A couple years ago Google tried to clamp down on comment spam by encouraging bloggers to add the "no follow" tag to links embedded in comments. The "no follow" tag tells the Google bot not to follow these links - making them much less desirable from the link juice point of view.

Many bloggers obediently fell into line because they were intimidated by Google threats. But some resisted either silently or openly and left their comment links intact. These are usually referred to as "Do Follow" blogs.

If you can find a "Do Follow" blog that still has Page Rank, leaving comments on sites like that is generally considered worth the effort.
