I think it's kinda funny that most of the tessellations are just using pentagons to make other shapes that tessellate naturally. I suppose the same could be said of most tessellations though, but it's still interesting.

The mobile version is very readable on a desktop browser, and it's probably easier for you to edit the URL on your PC than for the poster to edit it using their phone.
Assuming that the total effort expended by the few who really dislike the mobile interface is less than fiddling with a URL on a phone, plus gratitude toward the person for taking the effort to make the post at all.
