I've been going through The Linux Programming Interface (for about a year now, still not fully done!) and Kerrisk is a great technical writer. I'm looking forward to anything he has to contribute about software development (though I'm not a kernel hacker and never will be) and embedded interests.
Admittedly I've been slow to renew in recent years when my subscription has expired because it's starting to feel like "same old stuff" syndrome and I occasionally have doubts as to how much I actually need it. This seems to be a positive development though and if it pans out I'll renew quicker next time.
