By in large, my tweets are of links with some comment about those linked news articles. I would say that I could stand to be a little less critical and perhaps tone down the sarcasm a bit, with regards to judging some of these stories. However, I would not say that I am being unprofessional in some of my comments.
In terms of bolstering my use of Twitter I could engage in more news-worthy tweets. I think that I could tweet more actual news information, rather than tweets of articles, and thus, be less critical of others’ work.
