I have a hazy recollection of eWorld, but don’t think I used it. I don’t remember AppleLink-Personal Edition, but I did use GEnie for a chat group and perhaps for email.
There were all kinds of services in the mid to late 1980s. A major reason why I bought my first Mac (512K) was to get an electronic connection to a magazine I wrote for in London. Western Union had a service called EasyLink, that I used for a while, and Software Tool and Die, which was among the first companies to offer an internet connection anybody could get.
