Not a bug, but...
The publishing date and time is apparently the only used to register and ordering instructables. But there is in reality another date-time, those of showing in the web page, after the revision process. When I choose ALL RECENT daily (my default option, many times each day), I see the last instructables showed in the page, until I see others previously seen. That method shows almost all new instructables, since there are eventually others that where published a day or two before today, and they are some pages below. but showed today.
In fact, some my instructable has been showed one or two days after its publishing, and it was possibly missing by many persons.
I still think Instructables is one of the better (or the best) managed site in the web, but this features is a little annoying, because it forces me to look some days back, to avoid lost some very interesting thing. That happened to me more than once.
The solution is conceptually easy, I don't know how hard it is technically:
- To add to the database the showing_date_time as an attribute of each instructable, and ordering RECENT by that date-time.
It is not valid to replace "date-published", because that date-time is essential in case of authorship dispute.
