Yea, exactly. My point is not about its reputation .. Tumblr was not designed for traditional blogging. It has no commenting system for example, just a "retweet"-like feature; I forgot what they called it. It was aimed more towards teenagers and young people - as far I can tell. It just happened to have these very important features: - Post in markdown - Good looking themes with customization As far as I can tell, that's really it! If you make a platform that just provides these two things all the YC startups will probably use your new service instead of Medium or whatever else they are using.
