It could just be me, I'm in Galveston, but working on a large renovation project here, I noticed that noone used the internet/social media in any meaningful way.
The project had multiple cntractors working on it, lots of helpers/skilled labor, insurance adjustors/reps, and of course the homeowner.
Some of the contractors were from "out of state", I saw them on extended phone calls describing how the project was coming along, where they were at on it, etc. I couldn't help but think that a digital camera would have come in handy.
And maybe an intranet of some sort, so that we could all talk to each other, in (semi) privacy. As a carpenters helper, I wish the contractor that I worked for used social media, so that he could provide me with a positive review/testomonial of my good work
