With donation, webcomic creator will have two potential revenue sources
1) Ad revenue through PrimeTime
2) Fan Donation
Tapastic creator Introducing Emy has found success with Patreon (fan donating site) with her webcomic. She wrote:
I use Patreon and so far I've really enjoyed the experience. My
Patreon for my primary webcomic, Trying Human, is here:
http://www.patreon.com/introducingemy I only make $100 give or take
after taxes and Patreon's fees but it was a $100 a month that I wasn't
making before.
I believe if Tapastic add a donation button to each webcomic, it would be a win win for everybody.
There are many readers out there who would love to donate to their favorite webtoon creators. More webtoon creators are able to make a full time living from ad/donations, there will be more frequent releases for readers. Instead of working a 40 hours job, the creator can use the time to make and release better webtoons. More creators releasing webcomic = more web traffic for Tapastic.
Thoughts?
p.s. If Tapastic does introduce Fan Donation, which webcomics would you donate to?
