Thank you for taking the time to test this out and giving your feedback. We're fully aware that this will be a barrier to many larger bloggers and content creators. Imo, the steemit rewards will still far outweigh the seo penalties to small and some medium sized blogs, but this is certainly one of the top things we would like to see addressed to allow further growth of STEEM implementation tools for other websites.
Ideally, people should be able to use the blockchain for their creative content and be completely indifferent as to whether or not it is also displayed elsewhere, and instead see the extra front ends that display their content as a pro rather than a con since it allows more people to see their posts and people should be able to engage with it by "logging in with STEEM" so that to the readers you wouldn't really know what website people are engaging from, only that they engage with it.
100% agreed :)
I will still keep using your awesome plugin, just have to be careful for now to not make Steemit outrank my actual site that pays the real bills :)
