They probably feel like you when preparing these too. The reason it excels is that a few of the individual tweets go viral and it drives the complete thread.

Twitter could provide a long-form writing platform where you write the whole thing and then some tweets you want to package with it. I suspect they feel that this is a form of experimentation where any of the sets of sentences could go viral, but the author may be unlikely to select the correct ones most of the time.

I don't get it either, I miss when everyone had their own blog and we used RSS. Aside from the obvious decentralized and readability advantages, I miss that each had a different design, personality, style.

But I've long given up, since all the smart people chose Twitter to vent their minds. It's the only social media I've caved in to.
