 yeah i would much more prefer if there were a like button. i really like that we have the option on facebook, so i find that it to be compatible with my preferences. while it would be be nice to have the "like" button, i think that being able to comment on other people's posts is good enough.  this option allows us to elaborate and go deeper rather than just simply state whether or not we agree with each other's posts. while this may decrease the number of comments that we receive, one can assume that the comments that are available are substantial, have some sort of reasoning to back up their argument, and incorporate their opinion.
