The point of a blog is whatever the author would like it to be. It doesn't have to follow a structure or expectations. We just happen to be consuming it.

> Sorry, what's the point of this blog?

Being a blog the way the author dreamed of it.

> I hope people would write a quick abstract/summary in the first few lines and then go on elaborating.

I hope people continue doing what makes them happy. It's their site, they owe nothing to anyone (maybe except hosting / network fees, but that's not my business, either).

> Or at least put that summary at the end, in old-fashioned way.

Or maybe people can spend a couple of minutes to read and understand it, with the MSI (MeatSpaceIntelligence) which comes bundled with all human beings.

It's free, too!
