LinkedIn has diluted its branding
Have you added your blog to your Linkedin Profile?The question was raised on the LinkedIn Bloggers YahooGroup message board.
Note: The ability to do so arrives courtesy of TypePad's BlogLink. I use BlogLink, and here's how it looks on my LinkedIn profile:

As I'm typing this post, the LinkedIn Bloggers YahooGroup discussion thread continues.
Note: We did agree that "Cheerio blogging" is a nuisance, which adds nothing to professional branding.
I had Cheerios for breakfast today. ... The cat walked across the bed. ...

In addition to adding my blog to my LinkedIn profile, I use the "Web Site" fields for my site, blog and resume. Yesterday, I added SlideShare to my LinkedIn profile. Why? Because I believe that each improves my professional creditability and positive branding.
That said... as I look at my public profile, it is starting to look cluttered. Add in the increasing number of sponsored LinkedIn advertisements, and my profile looks like a filing cabinet with too many drawers of stuff.
LinkedIn's value is to get the most from your professional network. LinkedIn is a pyramid relationship manager, where as Facebook is a social community in which reciprocity is more personally than professionally based.

However, in its attempt to compete against Facebook and similar social communities, LinkedIn has "lost its way." To be all things to all people turns innovators into wannabes.
