It is absolutely not our intention to mislead anybody, therefore we will start putting the disclaimer on the top of the article if this makes you happy.
Our purpose is to inform people about these articles and even try to direct them to the original site... We strongly disagree with you that there is no value in that. If you look at some other sites like @Zer0hedge you can see that there are lots of people that appreciate this. Further if you can convince them to come to Steemit that would actually be great. Untill that time we think we are providing a valuable service for next to no reward.
If you want to improve Steemit, it might be better to start addressing problems regarding "vote buying", "voting bots","misuse of SP by whales", "raping of the reward pool" and huge payouts to posts that really add no value at all. This would actually improve the value of the system. These are the main reasons new users leave in huge numbers, not creating awareness for a very informative site.
