While this isn't earth-shattering news, it is another example of the influence of social networking: With the growth of social networking comes a change in blogging protocol. In the past, when mentioning a person in a blog post, bloggers would have to decide where the hyperlink would direct the reader, usually to the person's website, or blog--if they had one. Sometimes the link would be a direct link to person's bio page or "About Me" page on the blog or website. Often, there just wasn't a good link. However, the tipping point is coming as more and more hyperlinks are now directed to a person's on-line profile at one or more of the popular social networking sites. With this explosion of on-line profiles, it is possible to mention more people and add more links to blog posts. That, too, can benefit the search rankings for the blogger.
Just one more way social networks are changing the way people do business!
