Looking from Tumblr's perspective, yes over 4 years any company is bound to make technical mistakes. Should you sum them up in a blog post and say they suck? Probably not.
I am sure the documented mistakes over the years have been resolved and fixed. It's understandable that this person is frustrated--Tumblr probably should do a better job serving it's power users who remain loyal and helped create the community it has.
