You're talking about the "skills" section. I don't need to work with jQuery directly to know John Smith wrote my company's jQuery code and he has that skill. If you want to write an in-depth review of John Smith's code from a technical standpoint, you can do that on LinkedIn, too. Most often, LinkedIn asks me if they know XYZ and either I know that they know it or I don't know--the value I get from that, it helps me to see where my connections are going with their careers. That's helpful to know for a variety of reasons, use your imagination. Sometimes they go into "skill" areas I never would have expected. Likewise, if someone hates Java (even if they know it well) they're not going to list it as a skill. Also, you can turn off any profile section you find annoying, it's in the options/settings. For example, I have the "people who viewed PJ also viewed these profiles" turned off.
