In reply to Daniel Cotillas Ruiz.

Since it's my own site, I can write as much as I wish, but often for Twitter which has character limits, I'll manually syndicate a shorter version with a link to the original.

You might appreciate these two prior posts which cover at least some of the workflow: Threaded Replies and Comments with Webmentions in WordPress and Threaded conversations between WordPress and Twitter.

There are potentially hundreds of ways of handling it all, but since I own and control my own site, I can pick and choose how to do it. To my knowledge, no one has automated a way of doing replies within traditional "Comments" sections on WordPress to Twitter, so I do it manually, though I suspect that one could use Brid.gy to do it.
