Some calculations based on the prolific posting habits of JayJuanGee
Based on the profile of JJG he has made 25 491 posts to date at the time of this post.
With an estimated average word count of 400 words per post:
25 491 * 400 = 10 196 400 total words posted
Assuming an average typing speed of 40 words per minute:
10 196 400 / 40 = 254 910 minutes spend typing posts (Excludes time spent formatting posts and reading replies)
or 254 910 / 60 = 4 248.50 hours
or 4 248.50 / 24 = 177.02 days
JJG started posting on bitcointalk on 18 February 2014, or 3 047 days ago.
254 910 minutes / 3047 days = 83.66 minutes per day on average spent typing posts
A typical book has 300 words per page: The Bitcointalk book of JJG would be a monster at 10 196 400/400 = 25 491 pages long or 2.55 meters thick from front cover to back.
This is the definition of POW.
....and its 95% waffle.
I have often had the thought that he would make his point far more effectively , by making his post more succinct.
