LinkedIn's official blog had a post today called LinkedIn Profile Makeovers Just Got Easier. If you are on LinkedIn, I highly recommend you take a look at it. If you aren't on LinkedIn that is another conversation.
The makeover tool didn't identify that many things to improve, as my profile has been pretty complete. But I see way too many profiles that just don't have any information about what the person's skills and capabilities are.
Let me know what you think.
