So I see that Dylan Stiles is going to close down his blog next month. I'll miss it, but I can't say that I'm completely surprised by his decision. He's in the home stretch of his PhD work in a demanding group, and there will doubless be some stretches in the next few months where he'll be lucky to have time to go to the john, much less update a blog. I wish him luck, and hope that his eventual transition to Dr. Stiles is as quick and painless as possible.
And yes, that's my theory as to why he's calling a halt. I'm sure that questions of future employment and so on have crossed his mind, but his kind of site definitely won't hurt his prospects, should he decide to go into industry. Dylan obviously knows his synthetic chemistry, enjoys doing it, and can pick up new material quickly - those are some of the key things that you look for when you're hiring. I second the suggestion made by one of the commenters on his site that anyone who's offended by the blog is someone you wouldn't want to work for, anyway.
When I first linked to him, I wrote that it was a good thing that the internet didn't exist when I was a grad student. I meant that two ways - first off, I'd have wasted huge amounts of time rooting around on the web, naturally, not that I didn't make do with what was at hand. But the second problem would have been that I would have probably been tempted to start a blog myself, which would have taken up even more time that I couldn't have afforded. As I've written here before, the purpose of graduate school is to prove that you can get out of graduate school. After allowing for a certain amount of down time needed to maintain your sanity, things that distract you from that main purpose are not your friends.
If I'd had a blog, I'd have spent a good amount of time venting. That surely would have gotten me in trouble sooner or later, given the amount of steam that I had available. I'm pretty sure that I wouldn't have wanted future employers reading what I had to say after I messed up some reaction at 3 AM, what I wanted to do to my summer undergrad student after he blew us all up, or after one of my ever-helpful labmates had stolen a lab jack out from under a distillation of mine while it was still going. No one knowingly hires someone who sounds like a cranky, hyperverbal maniac, which is what I sounded like much of the time back then. (My current co-workers who read this site can, I hope, restrain themselves from further comment).
As for my situation now, well, I blog mostly at night, and I post from home. That's because "night" and "home" are real times and real places now, as opposed to graduate school, when they were crammed over into that little area on the left-hand side of the dial marked "Not in the lab, for some reason". Life's extras fit into place better after you've had the time to get a life to fit them into.
