One of the best things about blogging is the practice we get as writers. Blogging allows us a stream of consciousness. At the same time we can explore ideas that pop up and share them. They are not always popular, but by tapping into this flow of creativity, we are able to connect with issues and topics that are not only interesting to us, but often may be a kernel of information needed by someone other than ourselves. This has happened to me on numerous occasions.
Trust those first thoughts. They are often the most interesting, before we allow the ego to tell us they aren't good enough.
