There are a lot of weird comments in this thread but to me this looks like a cool, genuine project which has an obvious need; I don't think the vibes are off at all.
Given that lately I can't even be bothered to write Markdown for my static site I'm looking forward to giving this a try this weekend.
Yeah, I'm one of those commenters. I do believe its a genuine project made by someone who cares with the intention to make something lovely for the world. I believe the people who are making this are good people.
Its just that the marketing copy has some of the breathless silicon valley tone and organizational structure to it like its selling a product which grates against the quirky, personal, community-first vibes of indieweb.
And hell yeah! Any excuse to put something fun on the web is a good one, excited to see what you make :)
