There can not just be one type of online strategy used. We must use the tools appropratly and efficently.

I think technology strategies and techniques should not be any different.

Exactly! We must make clear what we will and will not except as appropriate pieces of social interaction. Posting "I agree" is sometimes appropriate and sometimes not.
