Someone contacted me on Twitter and asked if I could add a length, which I did (starting with the latest).  A very smart idea from both of you!<p>The idea of categorizing by length is great, and I&#x27;ll do it, because it&#x27;s so easy (well, moving forward).  However, most of these talks are conference talks, meaning that about 80-90% will be about 45-60 minutes long.  So it&#x27;ll probably be most useful for the outliers.  But again, it&#x27;s easy to do, so why not?<p>Thanks for your interest and suggestions!
