I also used to spend a lot of time searching for new posts live on the web and missing lots, especially if I had been away for a few days. I find that subscribing to the daily summary really helps, and also requesting that I receive copies of responses to my posts. Now I can scan the mail summaries for anything interesting, and file anything I want to keep. I then research any responses I want to make, and only then make the web connection. I am lucky because I have a fast and cheap connection (thanks boss) which means I can then refresh the main index every couple of hours and take a quick peek. I am time shifted from most of the board, (though I do worry about how much sleep some of you are getting) which has pros and cons.
