This is a great brainstorming tool for doing light blogspam-style "journalism", if your readers don't know about it (which they probably don't). Draw something with a rather unlikely looking feature— a graph that strikes the reader as quite definitely not just random noise. See if you get anything interesting in return. If yes, conjure up a backstory, and write up a post in a confident, assertive tone, that closes with the graph as your "care to explain this?!" evidence nailing home your suspicion.
It's not necessarily as bad as it seems because this is relative to overall search term popularity. As more non-techies adopted the Internet, the prevalence of all techie topics declined, some more than others. E.g. Python is more popular as ever, but it's search term interest peaked in 2006, even though it's absolute search numbers increased nicely.
I don't think google do trend graphs for absolute search numbers, so one way to approximate that is to compare the graphs for competing terms using Google Trends (1). So to get a feel for how popular Python is, compare it's trend graph to say Java or Ruby.
Another factor I suspect may be relevant for Linux is that the rise of prominent distros has probably sapped away search term activity for general searches for Linux.
I believe twitter didn't start seeing crazy growth until 2009 once they focus on activating their users and moving away from the idea that everyone needs to tweet to use twitter.
Just Google these words and add the word 'summer' to get some ideas. Here's what I came up with:
Bruising: More children play outside in the summer → more bruises → more parents/children(?) Googling for it.
Brown spots: Might be referring to brown spots in someone's lawn due to the weather? Or summer freckles?

My favorite linux is on the rise, albeit from a tiny baseline:

seems "Ubuntu" hasn't fared quite as bad? http://www.google.com/trends/correlate/search?e=ubuntu&t=wee...
EDIT: Seems Ubuntu may have overtaken a huge portion of Linux searches, but maybe growth started to fall off with the introduction of Windows 7? http://www.google.com/trends/explore?q=ubuntu#q=ubuntu%2C%20...
