Interesting talk, nice delivery.

Very informative and great examples and explanations! Good job!

Very well done, Stelian! Everything was good, but I especially liked that you covered even the small details. Which is why I think you'd appreciate these suggestions:

You touched on some privacy caveats (i.e. not logging cell tower IDs without consent, not logging session IDs, etc.), but those were just bullet points scattered around different slides. I believe it'd be better if you dedicate a part of the session to talk specifically about privacy.
Bonus tip on that one: People are used to their username being already populated in login forms and some would start immediately typing their passwords, often resulting in a password being submitted as a username, so it may be a good idea to avoid logging usernames too. Automated field-focus via JS makes this problem worse sometimes by artificially moving the focus to an already filled username field.

The part about date/time formats can be polished. If you remember that moment, I was that guy who asked if you meant a UNIX timestamp by saying just "timestamp" ... that was a bit confusing because "2015-09-29 14:15", as well as everything else that marks the time is also a timestamp.

Interesting talk with good hints for logging data.

The main thing I took with me after the talk is that while I try to be consistent with the logs I need to think even more about it, collect them and check them regularly and not only when something goes wrong.
