It's incredible how the internet's anonymity promotes stupid, immature and jealous comments from people. Do you ever consider that the running community is extremely small, and is always in danger of being marginalized? Why would you hate on the successful runners? Knocking them down does not necessarily translate into your gain. It might just mean a further decrease in the public consciousness of running as a viable sport to follow, and thus an even smaller advertising budget by the big companies that provide endorsement support for folks.
Yes, Lauren Fleshman may grate on some people. And perhaps she doesn't use correct grammar on her blog. And, yes, she has for sure forged a stronger brand and identity for herself as an athlete than many who have more medals than she. However, she's managed to do this via smarts and personality. Oh, and some small accomplishments as well, such as multiple NCAA, national, and Diamond League titles.
So drop the hating. Try doing something positive and useful with yourself. Or were you the types in high school who bullied others and dumped them in trash cans, just because you were young, and stupid, and because people can't fight back?
