I will be developing offshoot variants of this main logo for our niche markets, so this one logo may wind up being two or three down the road. I already need the second one, actually.
For starters, our logo of six years was red and black (with and without our mascot). While I am not married to those colors, they might be more identifiable to people already familiar to us. Again, not required.
I like Emblem and Combination style logos (as per 99Designs definition). Lettering arrangement can be straight or curved. The logo should convey professionalism, but maybe a little business casual... commercial but not corporate.
I like 3d elements like letters, shadows, etc for a more modern and stylistic look. I like chrome and metallic finishes or touches, too. Thick lines. Outlines. Shading and shadows. 3D or 'raised' elements. Modern, not folksy or traditional.
Since I have dumped the 'skyline' idea, the iconography should be servers, computers, technology. Not a big fan of the 'connected nodes' idea.
The logo should convey thoughts of technology: computers, networks, technology.
Please look at the design inspiration logos above. I keep looking for better examples than these... and can't find any. If your logo idea doesn't have the same general form of those, don't submit it.
EDIT: I have dumped the skyline idea. It's apparent to me now that it can't really be done or I can't describe it accurately enough. Apologies for the false start, I am not a designer and was just tossing an idea out there.
