Just played around a bit adding tags to an old series. The site seems to be picking up the posts fine! I did notice that the tags need to be within the first five, which is important when using an interface like PeakD where more are allowed.
The big problem I have at the moment is it seems to not be rendering my main comic strip images. I even tried reloading them as the link path might have been outdated.
Image is rendering out fine on other front ends, and Inkito picked up the first strip fine as the frontpage thumbnail image, but not within the content itself.
The only other two design/UI notes I have at current are that image sizing needs to be adjusted on desktop somehow. Portrait orientation pages of yours are so big I can't easily see them all in one shot which is particularly troubling when it's a big image or splash page.
I don't know if this means a zoom tool, or max width adjustment. Max width though you'd want different specifications for landscape formatted content.
And lastly, the footer with creator links and info should probably be a sidebar or a "floating" footer somehow. With the continuous load feature you have now, it's almost impossible to see or navigate to, especially with content that has lots of installments like your stuff!
Overall, very impressive start with lots of potential. I'm so impressed you've been learning web development and coding on the side these past years. You rock!
