I run my content through www.reverso.net for spell and grammar check, but I guess it is not perfect. I will work on my grammar.
I believe this is a very small fraction of the people I am describing, when you write 100 comments "good job bro" you obviously don't read the content, you do it for the eventual reward.
A great idea, but it is not feasable for the blockchain. It would be like facebook to have multiple domains.
I don't see why its not possible, facebook at least has language settings.
Like the KR and CN tabs are completely useless if you don't speak their language. I think if language was a setting that you could filter by instead the site would be much more user friendly.
You are right though, there are plenty of people who add nothing to the discussion and only want their few cents.
Yes, you have right ! User friendly steemit is the key for growth! Although I think adding features is a pretty slow process on Steem (not only this blockchain though) We will get there slowly but surely.
