Well I too am not a tumblr fan but I thought the article was interesting and being from a well known person in the boa and reptile community like April said, I definitely give it credibility.
And Reinz, assuming at minimum a 2-3 week period is needed for a boa or python or completely go through the "feeding cycle", I would bet 90% of the people who own boas or pythons as a whole do overfeed. I know i'm guilty of it myself as well.
