I'm in a slight mood today, so I'll happily answer with a list. In general, people should've always considered having multiple places to look at when it comes to posting comics. And yes -- that also includes making your own site if you feel other sites just aren't what you're looking for. So here is the list:
Webtoons
Tapas
ComicFury
GlobalComix
DuckComics
Hiveworks (which is submissions only)
Leshin (also submission only)
Your Own Website
Posting to Paetron
Posting to Twitter
Posting on Reddit
Posting on Tumblr
Note: If there is more, others will add to it. But these are the ones I know of.
No one here (including me) has limited options. Instead, most people acknowledge that certain sites gain more attraction (and hence more supporters) than others. That's just a fact. So if you're looking for a bigger audience, places like Webtoons and Tapas are your best bet. If you don't care about that and want to customize your site, places like Comicfury, Tumblr, and building your site are other options.
In the end -- you do what is best for your own comic. That's it.
Happy Holidays, everyone. Hope you all have a lovely day.
