Is participation, in blogs and forums, from companies offering products/services a good thing or bad thing? Do you like to see companies, whether it's the CEO/President or a staff member, engaged in topics on forums/blogs. Do you consider it spam or do you consider it educational and helpful? Does it help the industry, as a whole, when companies are transparent? Do you know of any other industries where the CEO or staff representatives engage with their customers in forums or blogs? Is it good or bad for companies to engage with customers or potential customers through forums/blogs? Thoughts?
