So, I made this post, however as often happens when a question is posed on line, I don't get a response that answers the question. This is not a criticism as often I do get an answer, specially if the question is a bit easier to resolve.
So, I began to think of how I might solve the problem. I had searched for some key words, however there was one aspect of the search function I had never used and thinking about it, I should have.
I went back over the keywords I had used before, this time selecting the People you follow option. Finally, the keyword talk, brought up the tweet I was looking for.
Thanks to Craig Badura for his creation of this presentation, and thanks for pointing out a new app, Smore, that might be useful.
Love Twitter, and love to have learned something new about searching for a tweet from a member of my PLN.
