note that there is also a reputation paradigm to keep behavior in check and many other factors go into curation. it can be the timeliness of the post, its impact on community, whether there are resouces about the topic, the target location e.g a post from China may trend cos internet may be censores in China. the technicality of the post as well, the behind-the-scenes in relation to the post, the consistency of the author, its impact in the search engines, steem growth etc note that we also have an entireemail audience in the search engines and one major aspect of steem growth is organic traffic from the search engines, so a post's performance may be look at too. plus, what is rewarded on steemit is value and value takes different formats "content" being of them and "content" in itself, takes different formats, full-blown blogs being only one type of content being that the actual beauty here is the steem blockchain itself around which as many apps for as many types of audiences can be build. so steemit.com isnt the only app but bein the first abd major app, all content from every condenser appear here. so yes a online wobt be considered junk to zappl cos it is a twitterlike app built on steem and they may decide to have their curators seek those out, a few pictures may not be considered junk by steepshot cos it is an instagram-like app build on steem and they may decide to seek out those forms of content. we already have more than 300 apps on steem and more to come with the birth of smt and communities and well, every content from these apps appear on steemit.com. so yes even a red tomato image may be consideredconsider more technical as a trender than a thouaand word blog on feb 14. curatiob overall has a fan side factor, so overtime curators actually become fans. some curators look at the investment aspect as curators get rewards simply for upvoting (further) evidence to value being ehat is rewarded. yes, contribution is also a type of value so someone can be rewarded on steem for things done behind the scene even if his post is not a so-called perfect blog. e.g a developer may have complete an app requiremebt anf get upvoted on his very next vlog.
