Took me all day yesterday to put all the pieces together, but I was finally successful in my efforts to get my LWC weather data uploaded on a timed schedule to Twitter and from there on to my facebook account.
I used a combination of a .php script and crontab. Crontab handles the scheduled uploads on a 30 minute schedule. I tried shorter intervals, but it just seemed too "spam-like" to suit my tastes. I figured a 30 minute interval was a good middle ground. If visitors want more rapid weather updates from my station, they can always go to my website where I have 2 second rapid fire updates on one page and 2 minute intervals on my main home page.
