When I write a post for dx13, I write it in plain text with a special markup syntax. Some hacked together regexes then translate my markup into bold text, links and the like. This solution was a duct tape and string solution, often meaning that I had to go out of my way to make sure the regexes could parse and format my writings correctly.
It is not unknown for me to miss a failure in the parsing and for bits of formatting markup to then end up in the published items. This is somewhat unsatisfactory.
Over the past few years, there have been several more powerful and robust text -> HTML conversion scripts produced. These allow for much better formatting control and much less probability of error (presumably) than my home-brew solution.
Only time will tell, and, of course, the quality of the writing may be more the problem for any sub-optimal reading experiences.
