Yes, I also have missed following the Phillies' minor league teams via the internet. I routinely checked the scores and box scores almost every day during the season.
For me, attending minor league games started in either 1951 or 1952. I attended my first major league games in 1950 (four games, double headers at Crosley Field with Reds playing the Phillies and the Giants). I started collecting some baseball cards in 1951 and I think followed baseball a little. By 1952, I was following the Phillies as the season started and collecting the nifty new size 1952 Topps cards. But in the early fifties, we spent summers in Nashville, so as soon as we got there in June, I listened to baseball via the Mutual Game of the Day broadcasts on radio with Dizzy Dean and at night, the radio broadcasts of the Nashville Vols. We attended several games in person at Sulphur Dell. I spent the summers of 1953 and 1954 as well as the school year of 1953-54 in Nashville, so even though I continued as a Phillies phan, my news of the team was very limited over much of those seasons. I mark my fandom from 1952, the season I really got interested in following baseball (Phillies and Vols).
My minor league games in person in the past twenty years have included several in Nashville, one in Memphis, and several in Beacon, NY (Hudson Valley). Since moving to Texas, I have probably averaged two Rangers' games a season.
The minors have undergone significant reorganization in the past but the number of teams has been stabilized for some years now. I guess we are going to see a big cut coming next season. Sad to see since minor league teams have provided enjoyment across the country for more than a hundred years. Times change and maybe the younger folks today find enjoyment in different things than we did.
