I read on CNN yesterday about Yahoo and Google planning to offer social networking applications through their email page functions. Both companies have already made significant strides in allowing users to customize their home pages and aggregate content and functionality from various sites into a personal portal page.  However, I think that email is at odds with social networking given that email is inherently a personal communication.  Sure, I can block content from being seen by the world on social networking sites, but content is largely available to people I’ve marked as friends. Email is often more transactional then social, and that is a significant difference. I get the point about my email contacts being the genesis of my social graph, but no offense, there are some folks in my contacts database that I prefer to communicate with only on an as necessary and transactional basis.  Now, having widgets that tie my social networking information into my Google home page would be something I’d really go for. I’m all for the idea of a centralized home page that is aggregated, and eventually curated, just for and by me.  But leave my email account alone.
