The author is an idiot.
ETA: I had a program manager who thought that having a blog meant the developer was an accomplished/published author. The developer quit for having to work 10 hour days after the first week and a half. Again, idiot.
Would their academic credentials have been more helpful?
I also caveated that comment: I may be missing out on some good candidates, but seeing something they've created is the only way I know how to screen design candidates. Perhaps that does make me an idiot :(
I'm not saying that having a blog makes you an "accomplished author" as the original commentator suggests I was implying, I'm just saying that seeing your work is the easiest/only way to screen for talent.
Designers design, and like to show off their designs. If a designer doesn't have anything to show off, it doesn't pass the smell test for me.
