WTF?!

I was looking to my latest post statistics, and this is what I got:

Where is the Internet Explorer? Is it dead?
Windows only at 49%?

I've been looking for all time statistics on my other blogs and sites, and it's tightly coupled with the content's subject and how it is being accessed.
Windows and Internet Explorer are mainly used by:

• people searching contents
• Portugal related subjects
• old postings

And are not (less) being used by:

• people on social networks (Google+, Facebook, Twitter)
• technical related subject
• recent postings

If this is actually a trend everywhere, and not just on my contents, then Microsoft might be in a deeper trouble than I thought it to be.
