My vision of the site was to help build a community where users were able to find unconventional and sometimes creative solutions to everyday problems when a typical solution (though sometimes regional) was unavailable.
Generic scenario
Here is an outline of a situation in which a user may find themselves turning to LHSE for help:
User is at a location doing a task and they have either lost, broken, run out of, or forgot their standard answer to finish the task. Are the extra materials, components, chemicals, tools, devices, products lying around at the current location to solve the problem, or is the user forced to stop what they are doing, and go to the store and repurchase/replace the "solution(answer) of choice"
Specific example:
Last night I made a birthday cake for my wife. I realized I didn't have any candles for her to blow out. I was faced with the problem, in a pinch, of what could I use to simulate candles on her cake and give the same "feeling" of blowing out candles". My solution was to accept defeat and give her a cake with a "2" on it used recently for our toddler's birthday cake. However, if I had more time, I could have gone to the store and bought more candles.
Example life hack solutions could have included using sparklers if they were around, or place 30 matches into the top of the cake, possibly making candles etc etc...
The point I am making is that if this site is to be about "lifehacks" we should be encouraging any question to be asked, and allowing the community to come up with innovative answers to the problem. I don't think we should turn it into a "challenge" site and race for the most obscure solution.
For me, in summary, the site is more MacGyver than Rube Goldberg.
