Thank you. I am a little disappointed that a relatively recent post I made, asking the differences between WriteRoom and TaskPaper went unanswered - at least as far as anyone weighing in to compare them with Jesse’s other apps. There was a very satisfying discussion about the actual writing habits which people use. I was also hoping to learn a bit more about WriteRoom, FoldingText, and TaskPaper and where they differed and where they converged. All I can tell about WriteRoom is that it gives a simple, focused, distraction free writing environment which frankly, doesn’t interest me at all.
I have done professional technical writing and editing so I know well that TaskPaper is not a text editor like Word, Pages, Nisus, et al. Those kinds of apps are still very important to me. Typinator however fits into a niche that I was previously unaware of, it helps me to organize my thoughts and my writing. With the LESS files giving me quite a bit of styling choices and the tags allowing me to separate out sections for various reasons, and with the folding and outlining that TaskPaper does, I am in Hog (Bay) heaven right now. 
I am sure that when I get this story all put into shape and the outline is clear, and the sections are in order, and everything makes sense, I will simply copy and paste it into a Nisus document (or Scrivener) and go the distance. But this current phase, this organizational phase, is where I have always stumbled around in the dark with my own work. Typinator has finally changed all that.
If what Jesse is thinking about in the future, write in styled text but save it in plain text, is like what Typora does, then I am all for that. Seeing Typora is the first time I have understood a practical use for markup. Before this it was always, write here, and display over there (later). Typora also uses CSS similar to how TaskPaper uses LESS. But, with the tags, searches, and especially the folding bits, I don’t think I will be leaving TaskPaper for Typora any time soon. I only present it here as an excellent example of what can be done in markdown. You can put plain text and styled text together, so it turns out you can have your cake and eat it too - after all.
Added: Because TaskPaper has a simple text, plain text, etc, heart, I have accepted that I cannot put graphics into a TP document. Sometimes I wish that I could, right now it would be helpful to paste in a flow chart graphic. But I accept that TaskPaper was not designed for this purpose.
It would be a huge benefit to bold, underline, or italicize items I am seeing that I still need to put my attention to. As those items are often in a paragraph or a block of text, there is no way to call out any element of text right now within a body of text, to focus on in TaskPaper. I can put attributes on a tag and add the tag - but of course this will affect the entire paragraph or line that the tag is in. Style in the way that I am referring to it is about focus more than it is about styling embellishments. It is the same way with this thread’s OP, shortening a link. Reading with the ability to focus on things that need attention - but not loosing focus on the reading, is what we are talking of here. At least, it is what I am trying to say.
