Instructables? or advertisements??
I just noticed an "instructable" on patching cracks in concrete, posted not by an individual, but by a corporation, Sackrete, which advertises on this website. I happen to like Sackrete products, and appreciate that this company produces videos to instruct its customers, BUT... this seems to violate the spirit of this website! Is it not dubious to allow advertisers to promote their products in the same format as those videos contributed by regular folks? Anybody want to enlighten me on this?
