I see that all the questions now carry a Google Plus logo, in addition to the Facebook and Twitter ones. However, unlike the older logos, I think the G+ logo is a little too bright:
I can tolerate the colour, but it does distract my attention from the nearby question. In contrast, I have rarely noticed the Facebook and Twitter logos that very much, which points to how well the UI has been designed in general. Kudos for the design team!
Do others face a similar issue? What would be a better choice of colour? My suggestion would be (some shade of) dark blue or dark green; but I am not good with such UI issues, so perhaps others have better ideas.
