Also, Mudbunny more personally, am I misremembering them NOT doing this from the start, and only beginning to do it after the community (including yourself and myself) rallied to get some accountability from them, waaay back when the mags were new (to WotC) and pretty sloppy?
Not them, but YES, the community did have to force to get some sort of calendar out in advance so people would know, as well as get them to even publish a table of contents. BAsically trying to keep some sort of resemblance then to a magazine rather than jsut random blog entires.
As to magazines and missing deadlines, you would think in the centuries since printed publications began, someone would have learned who to manage a schedule. Where news is concerned you can expect event to change last minute, but in regards to D&D, how much really changes?
Also if you are publishing online, you can give the same time alloted as if you were to print it, but copy and paste to the online database for the rules encyclopedia, character builder, and the article all at once, and jsut have it formatted, without having to worry about time to print, sorting labels and mailing addresses, and actually mailing them out.
Cutting corners to try to wait longer to do things, is what would cause the delays. With a print magazine you can't have lst minute article replacements without everything being off since the printers have to change things and refit things in order to print before they can be mailed.
Not being able to maintain a schedule just seems like the contractor to build a house deciding not to show up to do anything today, just cause he felt like it. Maybe not the best example, but as with that case, you sooner or later stop paying the people that cannot get the job done, and find those that can and pay them instead.
If too much is being given to one person to do, then you need to find more people to spread the workload to.
The fact that delivery and "printing" of a digital media, means you have more time to get thigns ready compared to a physical copy, but doesnt mean you should try to shorten the time to get it done.
A schedule can be made if it was really wanted to, but not wanting to make a schedule and stick to it seems lazy and uninterested in what it is you aren't making the schedule for.
