Yes, the liking and scrolling past your post without actually reading it seems to be quite a popular thing to do. I started on steemit in January and have been reading some of the post that are trending.
Yes I do acknowledge that there are some posts that should be there but there is also some rubbish out there and all that people are doing seems to be just slapping some images together saying "look what I did" and they get rewarded because they have quite a big following.
