Steemit used to have a second 30-day putout window and it was barely used. I don’t think old posts will gain much under this approach.

7 day, 30 day, doesnt matter. Having this kind of time frame to monetazing a content is not profitable, If the main objective is to have high quality content being posted here.

Content platforms (not social media) reward the creators as long as the content is up and running. Then there is no incentive to put an effort to build an audience here, since i would get a better return elsewhere.

Old content is still valued and valuable because it gains you new followers and votes on current content.

Maybe, but i dont think the impact is that big. Most of the times when i find some good quality, well written old post here on steemit, a Lot of the times the user doesnt even post anymore, probably because he went of to write somewhere Else where he get a better return for his effort.

Also, what if that post that i found googling was a good post, but the other posts of that users as shit? Should i vote for his New posts only because i likes that other one that i cant upvote Anymore?

I think this argumentos kind of weak.

Unlike other integrations on Steem, it doesn’t filter anything out. It shows everything.

But luke its no about the filter, but what kind of post/content is mainly published here.

If we Go the social media way, things as Just fine, and there is a Lot of front end working for that matter (i really like @steepshot by the way)

But then we, as a community should drop the "quality content" discussion, and use steemit for as Quick content platform, like sharing news, discussion, memes, pictures. (Spam and other abuses must still be fought though).

Its all about a clear direction of what is steemit as a platform is supposed to be.
