While the beauty of Twitter is in people being able to talk to other real people for business or personal reasons, that side of human nature that loves efficiency, tries to commoditize human engagement and interaction. The most influential and successful Twitter accounts, business and otherwise, are ONLY the most personal ones (hint, hint). Some businesses know this and do a great job. Some, not so much. The ones that don't do a very good job, either don't really care about their audience and are trying to make a quick buck, OR, they do care but are new to social media and hired the wrong agency to get them off the ground.
I have a quite a few keyword streams I watch for business reasons and lately I'm starting to feel like I spend more time managing my block lists and finding tools to combat garbage than I do discovering new and interesting people that I find valuable. My multi-column keyword search setup on Tweetdeck is now starting to look like a freakin' landfill of algorithmic chaos. Here are some things I'm seeing a lot of lately that are driving me nuts. Some of these are old, some of them are new, but all of these activities have more than doubled in the last 3-6 months.
