I think it would be good if
1) emails about comments included the text of the comment, so you don't have to return to mobog just to read it
2) you never got two emails for the same comment. (I get two when people reply to me on my own page, for example)
If you use this company's products or services, we'll add the company to your dashboard. If you work for this company, we'll add you as an employee. Got it, thanks!
