Folks who've used tour things like this: how do you detect if it's the first time your users are using your app? Do you make a db query every time they log in? Do you use cookies? Cookies seem unreliable and a flag in the database seems a waste of resources.

Thoughts?




We store a flag on the user that the tour has been seen. The user is always loaded with the page anyway so it's no extra DB calls to get this information.


Ah. Fair enough. Thanks for the tip.
