Twitter is keen to find ways to become more accessible to a broader audience, beyond the tech-savvy early adopters. The answer so far: images. Images grab the attention better than obscure hashtags and @ reply's, and - sneakily - provides a way around the 140 character limit on a Tweet.
The results, lots of poor visuals. This large headshot is an attention grabber, but I am not sure whether Twitter users will take the time to read through the dense bullet points.
