It's hard to say what I like seeing the most, but I can certainly give my reasons for doing/not doing all of these when I ready comics!
When I'm reading a comic with a long story line (ie, not wrapped up in that page), I end up "saving up" pages to read in one long sitting. I prefer to read ongoing stories in chunks rather than seeing just a page at a time. Because of that, my views, likes, and comments probably look "backed up" to the creator or like I'm a dead sub. Unless I think a page is super duper wonderful I don't tend to like every page as I go either, just because I want to emerse myself in the story world. When I catch up, I usually comment only on the last page I read. It's not that I don't want to engage with all the creators work, its more that I don't want to stop at every page to do it.
Because of these habits I usually pick and chose short form comics, either with no real storyline or short stories that are finished each page. Because I know the next page isn't going to be connected I won't be breaking my emersion to comment. Same goes for my liking habbits.
Finally, I don't always have a lot of time to read comics, so I tend to sub to comics that I intend to read/catch up on - so it takes a while for my sub to turn into views! I don't sub to any comics I don't intend to read though. Just thought I'd share my experience of using Tapas since I know I'm one of those subscribers whose interaction doesn't crop for a while!
