I admit it. I'm a raving advocate for classic/traditional shaving. I shaved with an electric razor for 30+ years until one day I got an old-style barber shave. The results were so dramatic, literally life-changing, that I immersed myself in the "hobby." I even started producing videos
on how to shave properly. I received many, many comments thanking me (yeah, and a few snarks and hates too). I almost feel like a "born again preacher" trying to convert the masses.
Once every week or so, I troll Google for shaving discussions in non-shaving-related places (and I use the word "troll" as in fishing, not as in the snarky-freak-underneath-the-bridge-hater guy). I'll use a series of keywords like "i hate shaving," "learn to shave," "how to shave." I'll also do an "ego search" with a keyword of "mantic59."
Admittedly I get a ton of search results, 99.9% of which are useless for my purposes: "adult" links (ahem...), blogs that are obviously Adsense Farms or otherwise blatently commercial, teenage girls talking about shaving their armpits, etc. But every now and then a gem will pop up that I can contribute to. So I do. The vast majority of the time I get a very positive response, and sometimes even a convert. I've also found some really interesting websites and blogs along the way--places like offtopic, somethingawful, ask andy about clothes, the tilted forum project, naked with socks on, etc.
