BACKGROUND: I've designed easily 2000+ logos; meaning paid, not on my free time.
Have a few ideas, but my suggestion would be to focus on and agree on the "feel" the logo should have, and the message that it's sending.
FEEL: Techie, Fresh, ...
MESSAGE: Dialog, Community, Code, Clear
VISUAL: In terms of a visual, I image comments bubble "talking" to each other and/or point to a block code of lines that appears to be text.
FEEDBACK:
- A "magnify glass" is old school, and may come off as being overly critical, singular, and a closed loop form of analysis.
- "Glasses" might appear weak, and are also old school.
