Running a close second to the choice I appreciate the more experienced and pass on my knowledge to those with less experience is I do not like the wording of any of the other choices. I guess we need to define the term "peers". If another EC is playing by the same rules as me, hiring legal workers, paying payroll taxes, worker's comp, insurance, health benefits, etc. then he's my peer and I have no problem imparting knowledge I may have that he doesn't. On the other hand, if he wins a bid over me and he's hiring day workers off the side of the road and not paying any of the bennies he's not a peer and he gets nothing from me.
Most of us here in the forum have voiced our opinions and imparted some of our knowlwedge to others who have asked for it. I see no problem in doing that. On the other hand, I'm not going to give a blow by blow description on how to do a job start to finish.
It might be helpful if we could give some examples on exactly what type of info we all are willing to share.
