I'm pretty split between the two. While I love Tapastic for it being my first platform to publish my webcomic, I didn't really get any engagement even after 3-4 months of posting. Those that did interact and leave comments whether critical or praising I really appreciated, but it was far and few in between. Most were friend from everyday life that felt obligated to start a conversation...I appreciate them for that. At line, while at times (as mentioned above) some comments were crass and unfounded, I saw a general overall engagement. It also may be a content thing. I saw my Manga take off at Tapastic a bit better than on line and my Superhero comic take off better on Line while weaker at Tapastic. However, the one thing I absolutely hate about Line is the anonymous voting/rating system. It allows for (like mentioned above) trolling from other creators who feel threatened or just simply hate. It got so bad during this current contest, I wanted to just down every comic ahead of mine, but I appealed to my Tapastic side and decided against it. Didn't want to become what I loathed...I only wish Tapastic had a rating system that was transparent, which would allow for another way to get exposure and categorize some comics that get lost in the stream.
I spend an incredible amount of time on my work, so it is a bit disheartening to not have people offer you feed back even after months, but so it goes I guess. I'm going to take time to check out everybody's stuff on here though, and I'm going to keep posting my stuff on both until somebody notices it. I love to create stories, and I'll keep doing that regardless of traction...though a little bit more would be nice. LOL.
