$890 / 121 posts = $7.4/post
additionally, i don't remember what day in january '10 i created my account but if we assume it is the 1st, then i'm at 705 days which is $1.26/day margin of error of thirty days since i could very well have created it on the 31st that bumps it up to $1.32/day.
however, this $890 estimate is on the far low end because i have no recollection of shipping costs or taxes. it doesn't include the sound card i have because it was purchased before i joined head-fi and i considered it at the time not so much an audiophile purchase as a nice upgrade for a necessary computer component. the figure also doesn't include DIY raw materials (pcbs and articles from BOMs, wood, cable, soldering station additions, etc.) and tools that i have purchased for audio specific projects or have worn out during the course of various mod projects and builds. because ostensibly they could all have other non-audio applications and while i may have acquired them with audio in mind, they are not specific; not specialized. and even if i did include these, i have completely lost track of how much i've spent on DIY stuff. i think a lot of the DIY forum people have incalculable numbers.
