Google's Go programming language - four months on

Well, if you look at their market share http://www.netmarketshare.com/os-market-share.aspx?qprid=9 The iPhone is only 0.5% of users, and that's probably much less in the rest of the world, same for osX (5% but only in the US). So Go not being far behind is not something that's entirely impossible.

Edit: Observe that the TIOBE index is not about the best programming language or the language in which most lines of code have been written.

The index can be used to check whether your programming skills are still up to date or to make a strategic decision about what programming language should be adopted when starting to build a new software system. The definition of the TIOBE index can be found here. http://www.tiobe.com/content/paperinfo/tpci/tpci_definition.... "

So it's not about developper support.

But the TIOBE index doesn't measure developer support.

"The ratings are calculated by counting hits of the most popular search engines. The search query that is used is

    +"<language> programming"

The search query is executed for the regular Google, Google Blogs, MSN, Yahoo!, Wikipedia and YouTube web search for the last 12 months. The web site Alexa.com has been used to determine the most popular search engines."

Go has had a lot of press in the last few months but TIOBE doesn't really mean anything else. It's an interest index not a usage index.
