So I just reposted a story about the halo seen in Hawaii. I found that story by reading my sparks (spark?) on Google+ where I've entered astronomy as an interest. The question is, would I have seen it reading my Twitter feed?
I scanned back through my main Twitter stream for about an hour, which is a typical short reading session for me. A long session might involve reading back through two or three hours.
Then I went to my astronomy Twitter list and read back through those messages, well into yesterday.
The story wasn't there, or at least I didn't catch it. (Granted I did a quick skim and didn't actually read the Twitter posts). Hm.
