Do you believe in coincidence?

Is it entirely due to chance that on my way home from work yesterday, while dodging cars and trucks on my bike, my mind was drawn back to an old, dead project I've had on the shelf for a year to host user-created maps of Vietnamese restaurants, shops, doctors, etc and build a social network around such a service?

Or that as I drove to Target to drop off my wife's subscription, a break-through concept - the "missing key" as I coined it - crashed into my brain about how to bring such a service out of the mass of mashups and into a unique niche that would truly prove useful to its users by adding new place/event notifications?

Or that when I got home I searched "social mapping" and found that Google's Latitude, an update to mobile maps that will track you via cellphone and broadcast your position to your private network, would be released tomorrow (that's today)?

Or that today I routinely opened my design feeds and inadvertently stepped into a screencast featuring Mozilla's Ubiquity, which is an experiment that in-part promises to bring mashups from site-centric status to user-centric?

Or that jQuery is just so frickin' awesome that even a dense-head like me might be able to pull it off?
