totally, that was most of the point.
i.e. stop. fucking. with. me.
That and if i get hit by a bus or get sick of their shit, i don't have to feel bad for just bailing as im now generally keeping notes that are pretty close. it actually proved useful to me in the end, keeping track of where i am one day to the next, and repeating things later.
honestly, depends. for scaling when you get traffic, you'll want careful stored procedures, views triggers, and timing of certain transactions. until you get too hammered, not drunk, the server... you can get away with whatever. depending on what you're deving your php with swapping queries can be easy. but overall, precise queries will give you less headaches over time. like anything else, more work now, or more work later?
also, was gonna comment earlier, to try and keep in mind crowdsourcing curation and moderation. it may not be a feature you want now, but in time, you may be very happy you had it in mind, at least, at the beginning.
