I've done sysadmin work as well and the context switching didn't feel as prohibitive. Generally I was using something like Perl, Python, Bash, etc... but rarely switching between more than one in any given day. With web development, I have to know HTML, CSS, and JS at least. I probably really need to know SQL. And I switch between those four (at least) every day, many times a day.
