I have been checking it semi-weekly and just did so this morning, actually. It seems like a failed/forgotten venture. The posts that are there aren't really tied together. There needed to be a more specific vision of what "Pack Less, Be More" meant, and I don't think there ever was. There also should have been promotion of the contributors and their topics of interest, to give people an idea of the writers behind it and what sort of content and style readers could expect. And there should have been lots of content lined up and post promos to encourage traffic and comments, which as you pointed out, has clearly not been the case.
I tend to give promising but currently disappointing sources of reading material 6 months to improve before I write them off for good. PM,BL is about 2/3 of the way there and it's not looking hopeful.
