It's much more common than when you were 22. Career changes, diff tracks through school, all sorts of reasons why people want to do internships into late 20s and thirties since the recent recession.

Companies are still desperate for top talent, and for specialized skills at growing firms (tech) that's especially true. We have interns starting with us in the summer at http://www.thinkful.com/ (edtech) and two of them are in or finishing masters' in CS from Columbia.

As long as you're not being taken advantage of by a cheap employer I think internships are a great low risk way to try a job and career.
