Although I use RSS to let me know when other webcomics have posted, I usually have my reader go directly to the site rather than pull the article down itself. As a result, I’ve found many sites are not all-client friendly (i.e., they don’t work well with all clients, mine in particular) or they are outright broken. A lot come up with invalid date (usually due to date format problems).
There’s an easy way to check your RSS feed, though; run it through an RSS feed checker. The one I recommend is w3.org RSS validator. Just enter the URL of your RSS feed and see what it comes up with. It could be a pass, a pass with recommendations or it will list bad entries.
Typical problems I’ve seen are bad or problematic date entries. Examples:
Fortunately, the RSS code in WordPress generates valid RSS (usually); so, you should be safe if you’re using it with ComicPress, comic-easel or any other plug-in.
It takes less than a minute to check and it may avoid you using some readers; so, give it a try.
I’ve added a Patreon Link page for the webcomics I know that are now using Patreon for funding. You’ll find it under the Resources pull-down on the link bar at the top of the page.
Why am I making this list? Because, frankly, Patreon’s search function sucks.
This does beg the question: why do I do better artwork for other people than I do for my own site? The answer is obvious: beats me.
