My two cents.
First, I might be considered someone who has no business using a straight. I've had problems shaving my whole life. I was never really taught how to shave. Had I run across this product a few months earlier I might have been very interested.
However, I knew people had tough beards and got around it, so I figured it was just my technique with a cartridge. In fact, I didn't even know what I was doing was not what you would consider wet shaving. I thought I was a wet shaver with a cartridge. After all, the foamy crap comes out wet out of a can.
I was just searching for a better way and ran across a video of a guy showing how to shave with a DE. I had never seen a DE before. After all, you don't normally talk about shaving with other guys, why should I know what a DE was?
Then I came across videos of guys shaving with straights and that's when I became intrigued and found Straight Razor Place. It wasn't to follow any fashions, at least not for me. In fact, I didn't actually get a DE until a few weeks ago.
So there's as many reasons for people starting straights as there are people using them, maybe more. One day, some guy watching the video in this thread may decide that he wants a different way to shave. Anyone interested in watching a video on how to shave at least has the curiosity to want to learn more. That's how a lot of us got here.
