The source isn't that important here...
While the business model of RHT does rely on the filling of open positions in a variety of companies, they don't do themselves any favors by overstating the demand. And while some polling numbers might be able to sway the perception of something, I don't see a CIO looking at these figures, and thinking, "Gee, everyone else is staying steady, I guess that 10% reduction in force I was planning should be shelved." That's just not the case, as the CIO's decisions are driven solely by the other executives in the company and the business model and forecasts. The only CIOs and companies this survey might impact are those who were on the cusp of looking for new staff, but weren't sure. This might indicate that good help might come at a premium and not be worth it, or it might mean some talent will be available since some people are going to get laid off. It's a glass half-full or half-empty type moment.
In all, I would say that the IT market is better than other fields, only in that IT was still recovering in the US from the shellacking they got after the tech bubble burst and the outsourcing of back-end and coding work to India, so it was already pared to the bone. On-site support, however, can't be outsourced, and it seems that's what RHT focuses on, and that's borne out by the results of what CIOs say they are hiring for. I would stay away from the CIOs that are hiring and don't know why....
