I came across this article in CIO Insight - 20 IT Skills on the Rise. See the figure at the bottom.

Interesting to note that SAP skills are on the rise. My thoughts on that is, may be the economy is starting to pickup. Business is starting to plan and invest in growth - spending more money to add capabilities and new functionalities.

SAP being an enterprise solution, could be used to measure (correctly or incorrectly), what the business mindset is towards spending more money to grow. HP's first quarter result seems to support the renewed business interest to spend more.

I also noticed Solaris skillset in the 6th position. Hmmm.... makes you wonder if this is a temporary spike to move off Solaris and onto Linux. Now that Oracle has bought Sun and all. However, I don't see any Linux related skills in the list.

I was also expecting some hard core development skillset to be on the list e.g. Spring Framework, RIA, .Net, etc.., but they are missing.

We can't take this as an absolute data on the trend, without knowing how this metrics were collected. But it is something to chew on amongst all the others - not that we are lacking on things to chew on.
