Netsteve, I am sure that in some cases and examples, it could be a good diversification strategy. Many of us have seen numerous cases it can easily cross the line into spam.
Sites that I and others have described often have no trace (or little) saying who is behind the site, who is responsible for the information, with really questionable tactics about what they do with your information and why the collect it in the first place.
They also often have almost identical content as their other 'sites' - just repackaged. Strategy for the company? Yes...but I think it can be easily argued that it's not useful to the user at all, and it has done nothing to build trust, transparency or display honesty with it's/their users.
