Shameless plug, but my startup Xendo (http://xen.do) connects into Google Drive, Evernote, Dropbox etc. and provides a single search across all of them. You can 'pin' content so team-mates will see specific items promoted to the top of their results if they're relevant to their search. Let me know if you're interested in following up.
We're going to be introducing a 'professional' level soon at a fairly low monthly subscription. We'll be announcing shortly.
Your stuff looks interesting, we should have a chat offline.
And maybe something informational (like "TLS-DHE-RSA-WITH-AES256-CBC-SHA" or "Capable of TLS with ephemeral Diffie-Hellman key exchange (providing forward secrecy) and AES-256 in CBC mode with SHA-1 for MAC" instead of just "AES-256") or (if that don't hurt business) a description or link like this https://www.ssllabs.com/ssltest/analyze.html?d=xen.do at "Find out more" (also, see, there are some suggestions to improve security, and you also have "http://xen.do" links in your HTML that makes browsers complain about insecure content on page)
Disclaimer: I have no relation to SSLLabs at all, except for using them (and considering them a great service) to ensure my TLS is okay. I have no expertise in cryptography. I have no serious experience with SEO or business advertisement. Just my thoughts.
Comedy implementation of the observation that there's a sizeable section of society that prefers the 2D - Facebook/Twitter method of interaction vs. real, 3D, interation.
the interesting bit is how the quality of the average tweet could be measured and whether or not there is a strong relationship between volume and quality.
I guess it depends what you mean by 'quality'. A methodology for determining 'quality' would be awesome, some function of timeliness, authority, context, accuracy. I don't see that quality is correlated with volume though.
