Are the chapman brothers friends with Jonathan Ian Mathers?

[Leplaya]

This has been asked but I'll bring it up, I know that the chapman brothers are famous for being known for Homestar but there has been one particular webtoon series that I wondered what the chapman brothers would think. Foamy the squrriel, what both Homestar and Foamy have in common is that they were made around when Flash animation was introduced. And I have been thinking if the creators of both these webtoons were friends...What do u think?

probably not. doesnt seem like the sort of stuff the chapmans are into, so they probably didnt go out of their way to meet this guy.

What the heck does the creator of Foamy look like anyways? I wouldnt be surprised if he was a guy who was a goth person. But chances are they are friends but probably not the type that would get along quite well.
