blogger street cred 

Short for "web logger street credibility"

1. The amount of respect you have gained from other members of your blogging community (generally a subcommunity of the overall blogger community, such as "video game bloggers")

2. A term used sarcastically because people who blog do so on the internet, which is widely regarded as the least credible source for information apart from televised news.

That dude totally lost some blogger street cred when he decided to post his views on violence in gaming, which every other video game blogger disagreed with.
