The problem with switching often is that there are good reasons to do it, and bad reasons forcing you to do it... That is, many people that read N books and look like experts at a first glance, but can't actually code tend to switch work very often since after some time they are "uncovered" and move away. There are other good reasons to switch often: being exposed to new technologies, getting a raise, and so forth, the risk is to be confused for a frequent changer for the reason she/he can't actually code.
