As a post title, I rather like VisiblePath is a lot like LinkedIn, except it’s useful. As a description of relevance to me, the title I use for the current post is more accurate. A service that depends on an Outlook plugin might as well not exist if, like me, you don’t use Outlook.
I did take a look at the VisiblePath site for other plugins, or other ways to use the service if you don’t use Outlook, but none were… visible. Following the link in the first paragraph of this post will lead you to other points about VisiblePath, both pro and con.
