I generally don't like the hot glue gun, but I think it's a great tool for certain uses. I use it a lot for prototyping, and then use other adhesives for the final build. But that's mostly due to my clumsiness with hot glue, which results in endless spiderweb effects around virtually anything I build.
There is a contingent that does not like grid play on the DM's Craft boards, and I have seen comments from time to time about how superior gridless is to grid play, but I have always taken that as personal opinions and not as criticisms of people playing with grids. Of course it may well be that I just don't care much if someone bashes grid play and so it doesn't penetrate my general armor of indifference, where other people may react more strongly to it.
What I like about the forum is the incredibly helpful vibe I've found there. I posted some stuff on the Hirst Arts board back when I first started making stuff out of Hirst blocks and I was very surprised by the negativity of some of the comments about my work. I've never had that happen in the DM's Craft forum, everything has been positive or at least the critical comments have been made in a helpful manner.
And I've learned a LOT about how to make stuff that is cheap, useful and in some cases, quite well done. I think folks who are looking for that sort of thing should at least check it out.
