Open question : brand trust / riding on the shoulders of giants

I'd like to ask an open question regarding customer trust in a brand. If you could spend just a moment and possibly post your opinion on the following matter It would be greatly appreciated.

I commonly see internet 'marketing' sites which feature a ribbon of 'as seen' logos, be it as seen on BBC or as seen in the Telegraph or many other iterations along that theme.

The idea being to instil trust into the visitor by appeal to an authoritative and recognised brand / name (Riding on the shoulder of giants)

now to the nub of this question:

Would there be any benefit to use this method, but instead refer to internet recognised brands. for example

As seen on -- Google, Bing, Facebook, Linkedin
(there are other possibilities but these are the big 4 really)

Would this self acclimation be a worthwhile thing to include on a site?

My personal view is... "so what"? Everyone can be found via bing / google and it's few and far between where a business does not have a social media element (even if that just means having a Facebook page)

but I need to know if this would be a valid tactic to earn trust of visitors to a site. I eagerly await your feedback.
