Some of the best science fiction stories I've read were in Analog. I've been a subscriber since 1995, and still have every issue.
Goodreads now let us rate and review each issue of Analog. I'll start doing this with the Jan/Feb 2013 issue, although I'm about six months behind in my reading.
I have a Kindle subscription to this, which is very convenient. However, the Kindle reader is MIND NUMBINGLY AWFUL for periodicals. There are no page numbers, no bookmarks or highlighting. On my older Evo 4G phone it loses it's place if I quit the Kindle app, but it has page numbers. Slightly better on my Nexus 7, as Kindle Reader doesn't lose it's place, but there are no page numbers. And what's with no searching the internet or Wikipedia with more than two words? Afraid we're going to copy a whole book three or five words at a time if we can use that for a search phrase? GAHH.

I've been a subscriber for 3 years now. Not every single story is a gem, but the selection is really high-calibre and it never disappoints. It offers science-fiction at its best, a literature of ideas, which is what it should be. Compared to Asimov's magazine, this one veers toward the hard sci-fi, with an emphasis on science. Asimov's is more focused on social / humanistic topics.
Good collection of sci-fi stories - favorite was one title 'how i spent my summer vacation' in which kids rebelled by playing outside instead of inside
