Can I just say that I'm a little frustrated with all of the vendors that come in and throw around the words 'SEO' and 'Social Media' in the same sentence without any real understanding of what they're talking about? I notice in the original post she mentioned that having a Twitter account would provide 'SEO value' -- to what extent? Please be more specific.
I always try to ask salespeople this question and most of them don't have a very good answer. Sure, the twitter page might show up on a branded keyword search below several other pertinent pages, but beyond that, what REAL SEO value does it provide? I understand that having a social presence is important, but is it really necessary for every salesperson to try and tell me that their service is great for SEO? Let's be honest here, you don't make a twitter account to boost your SEO. In our niche, having a strong twitter presence doesn't affect dealer website rankings very much. Let's just call it like it is and say that it's a branding tool.
