Whatever clue I dropped was apparently plenty clear because about 20 girls replied saying, "Wow, you're a girl? It's so GREAT to have other girls on this forum!"
While it may not have been the response I was looking for, I've seen this happen enough since then to know I dodged a bullet here. If I'd posted my picture, they would have posted their much, much cuter and girlier pictures. Had I gone with the less subtle, "Any other girls here?" I would have been forced to pretend I was happy to see all these other more attractive girls, matching their false enthusiasm with an even more over the top. "Oh my GOD, it is so GREAT to see another GIRL HERE!! ^_^ ;0) We'll all be SUCH great FRIENDS! Kekeke!" Every time I see it happen, some manner of disappointment ensues.
The Internet is even less like The Bachelorette than the real world. Somehow.
So exactly how rare are we delicate flowers of the Internet? A government study shows women have been represented on the Internet in the same percentages as we're represented in the real world since at least 2001. Great.
