How would you compare the theme of your magazine to something like Phoronix - which tends to be somewhere between Engadget and LWN in its "hardcore-ness". Possibly they are the Linux version of Anandtech (e.g. their efforts to bisect the linux power regression [1] as well as the Phoronix test suite [2] for benchmarks )

Are you addressing a more casual audience ?
