A more serious problem is the expression of a sentiment I think few of us here share:
"...not what someone on the internet tells you to."
Really? Is it really so bad or so unreliable to read what someone on the "internet" said? In fact, I think you'd find little in print that is up to date focusing specifically on a comparison of gitvsmecurial, and what's out there doesn't have comments replying to the most obvious weak points or updating with new information. A good, up to date, reasoned argument online from a reputable blogger-hacker? Reading someone else's argumentation isn't just about blindly listening to someone else; they may bring up new information or new points that you hadn't thought about.
And why does this sound like something a curmudgeonly old book editor might be saying about blogs and the Internet rather than a hacker working with the latest distributed version control tools?
