I have perused the 1 and a half issues (or so) that have come out in the past eight months, but I would not say reading it. Frankly, it is not worth reading for me now, for several reasons
1: It is online. I don't generally read pdfs for fun online.
2: It has no adventure path. I never played one through, but I liked the design elements.
3: The adventures have an eulogy feel. WE never had a chance to print this (no one would LET us print this) while the magazine was viable, so let's print all those old ideas we had floating around because it does not matter anymore.
I know that sounds harsh, but I liked Dungeon a lot, and I'm still quite angry how WOTC killed it, and then left it in the ditch to rot.
