Post same amount as other people in a thread or post elsewhere (my blog is my default). Otherwise I’m probably over or under sharing and either way it confuses people more than it helps.
For social groups – don’t give information, share my experiences. If someone wants information they can ask or look around on my blog, otherwise they aren’t ready for it anyway.
Don’t post links unless someone asks for the same reasons as above, there is somewhere else for that.
Drive-by is not a method to live by. Do it well or not at all.
