Are we utilizing the semantic web properly?

I was reviewing an infographic of how people spend their time online, and
it struck me just that most of the areas where the semantic web can shine
are under utilized:

Here's a breakdown:

22% -- Social Netwoking
21% -- Searches
20% -- Reading Content
19% -- Emails/Communication
13% -- Multi Media
5%   -- Online shopping


1. The semantic web is well suited to create user centric privacy aware
social networking with serious competitive advantages.  There is a great
initiative in the form of Solid [1] but we are probably investing an order
of magnitude less effort than we should be.

2. Semantic search is almost non existent (apart from SEO).  Especially
since sindice shut down.  But it's so well suited to finding documents and
especially multi media without having to go through the pain of search
pagination organization via documents.  I think there is a huge opportunity
here.

3.  I think we are doing quite well here making documents better
organized.  But it's a saturated space and tough to make an impact.

4. Communications and especially chat are almost non existent in our
field.  Why dont we have at least 1-2 phd students in this area?

5. I think the semantic web can blow away traditional multi media services
by providing smart indexing, ratings, recommender engines and having data
at your fingertips.  Again we are non existent here.  It's also a great
business opportunity.  New technologies like webtorrent [2] may also
provide more interesting distributions models.

6. Online shopping.  Well we are OK here in terms of good relations etc.
But again it's a saturated space where you'll need something special to
make the occasional breakthrough.

So my question is why isnt the effort in the semantic web community aligned
to what people actually do online, and can we fix that?
