I think it has been a great initiative to get more painted minis up on the CDO interwebs, both chaos dwarf and otherwise themed. For me it’s been a less effort option compared to @Oxymandias 1 or 9 million unique off topic showcases of which Tzeentch Ogres is still my favorite.
I agree with Bas (and basically all other comments above) for me personally I’ve greatly enjoyed a sorted catalog of my years work. As opposed to post and forget social media. Banter is great and the increase in hobby hangouts this year is an awesome side effect.
We all want to see peoples painted projects. Having pictures in the blog is really the only “rule” in my mind. Obviously there are extenuating circumstances why pictures might not be immediate (contests, waiting for that unit/army to be finished, camera recently pissed on, too busy writing OC for your doubtlessly one-of-a-kind DND character, etc).
For me at least, picture forum need pictures. (Or links to 9 million off topic showcase) grunts, beats chest, bonks head with club
