I am still new to BP, but I agree that colleague requests need to come with some message and/or connection. I don't mind connecting with people, but I would like to know why your reaching out to me.
In the short time I have been here, I have my own pet peeve that I would add: people that don't use the search function. I have seen several posts asking for help explaining a concept or methodology. Examples have been Crowdfunding or Sub2. There is a wealth of information on these and other topics, if people use the search feature. But some people just post a new thread asking the same question, as if to say, "I don't really have time to do my own research, so can you sumerize what has already been explained?" My unposted response is "if you don't want to put in the effort to research what's already out there, your probably don't need to be getting into REI, as it is going to take more work than searching BP."
I hope have not offended anyone.
