eh, from a SysAdmin point of view, popularity and familiarity are reasonable arguments. Certainly not the only arguments you should take into account, but the ease with which I can hire people who know the system, and the ease with which I can use a search engine to find answers to my problems is very relevant. I can't say I've been using squid for 10 years constantly, but I've used it on and off for 10 years. Just about any reasonably experienced sysadmin has used it some. Caching problems can be a little tricky, and having someone experienced with the caching system when something goes wrong can help a lot. I'd say squid is a bit like NFS. It's not the best system possible in theory, but goddamnit, it's been tested to hell and back in systems much larger than I'm dealing with, and we know where all the problems lie. (Also note, I believe Windows is only more popular on the desktop; Windows has never been a majority player in terms of webservers and other public Internet infrastructure, unless you count private intranets. in the public Internet server space, windows is fighting with sun and apple for the scraps. Linux is the big player here. )
