Ezera is just another decentralized blogging platform with a couple features. I have a feeling it's going to get popular in small niche groups, but won't beat out Steemit in sheer volume of activity going on on a daily basis. Steemit will most likely last the way Bitcoin did. Being the first success, it paves the roads for many other things similar, but it's also the marketing point to get people interested in that type of platform, so people will start using Steemit first before learning more about the blockchain and moving over to other platforms if Steemit doesn't manage to keep up with all the latest features like Bitcoin.
