Hey guys, this is probably the biggest technical blog post I wrote and I'm looking for some tips/feedback on how to improve my writing skills.

I'm also aware there are other ways to approach this problem, this post is aimed to people who are not very advanced when it comes to caching dynamic data.

Thanks!

The writing is easy to understand, but is there any reason why you're just not using memcache's add method? For the price of a network call, you'll automatically get the LRU cache logic and a more deterministic behavior.

  Thanks!
  For which operation are you suggesting to use add() method? As far as I can see (and I just walked in so I might be overlooking something) you want to set data (overwrite) if it exist.
  Add() will fail if key already exist (which should be the case under full load) and you will end up using set() anyways.
