How about a happy wallet surrounded by the words DansDeals.com?
Or better yet, have Dan try to synthesize into very short description what his site is all about, then try to brainstorm around that for a logo.
With all due respect, if you look at http://www.unifiedmediallc.com/blog/2011/02/top-fortune-500-logos-deconstructed/ you will see that most logos actually have the full company name, and design actually goes beyond it. Very few companies will use initials for the logo (GM - but they are known by that name - if I'm not mistaken, the only one that has initials which is not commonly known by the initials, except to stock investors, is ADM).
I am not sure how much background you have in branding, although it does seem you are pretty knowledgeable - either way I would not want this thread to turn into an argument....
The link you provided is from 2011, If you were to filter out fortune 500 companies to web-only brands like publishers, blogs, social networks - you will see that the majority of them have found a way to have a one letter logomark represent their brand.
For instance, I looked at my phone and say that over half of my app icons are just 1/2 letters vs a pictograph or icon.
When it comes to web branding, the approach is a bit different. You must take brand cohesion and visual identity into consideration:
Where will the logo display?
App icon, favicon, social network profile photos, bookmarks, emails, 3rd party sites, etc..
When do users NEED the logo to be clean & concise?
When scrolling through facebook feeds, switching between taps on desktop browsers, clicking on the bookmarks bar, or on mobile device home screens...
Here are some brands I use or identify with as a traveler and tech aficionado:
