Earlier today I announced the creation of a twitter hashtag, #trdev so people wanting to create a training and development community of practice on twitter could find each other, and interact. We have additional plans to make this work. However it will NOT work if the tag is used for NON-RELATED tweets.
Within 3 hrs. of announcing the tag, providing instructions for use, etc, Doug Constant @onpointcoaching started spamming the tag with messages of various types NONE of which pertain at all to the topic. You can see for yourself what he is doing by doing a search within twitter for #trdev, and you can see what appears to be a deliberate attempt to prevent you and I from creating this community.
