Hey guys, so yeah after reading all the opinions here about LINE and how a few have noticed more visibility there I decided to give the site a chance for myself.
Here's my experience. I've started posting my earlier/weaker issues of Oops so I'm not overly surprised that after a month posting there I have 72 subscribers, over 600 views [with absolutely NO promoting my presence there], 6.7 rating and zero negative comments. [low stats compared to other people's experience posting to LINE] In fact, I've gotten some really nice awesome comments there.
Additional thoughts, I feel like it's harder to connect with readers on LINE. There's no wall posting, 200 character limit for episode descriptions so can't write lengthy thanks or extra info. Most I can do is reply back to readers that do comment. So in that sense and being used to Tapastic setup, I feel more isolated from readers on LINE.
I think the negative side of LINE comes when you enter competitions, however as just another place to post a comic it isn't terrible. Each time I post a new episode, Oops can be seen at the top of the Discover page for Fantasy comics which is likely where most of the 600 views came from. Also a negative is that you can't schedule episodes to post, it must be published manually, however you can save "draft episodes" to make it easier to just publish later.
TL:DR- LINE isn't a quick answer for views/subs, however it is easier to be seen there without a ton of self promotion.
It's harder to connect with readers directly, and for the most part the community is nice if you avoid the competitions.
There are less site features to LINE compare to Taps like a lack of episode scheduling and wall posts.
I plan to keep routinely posting there and see where it gets me. All things considered I find it an ok site.
