Back to My Mac is a feature that is designed to allow Mac owners to connect to one Mac from another Mac for file transfers and screen sharing purposes. It lets users set up a network of Mac computers with two or more Macs, but it can be complicated to set up and use, which may be why Apple has decided to discontinue it in favor of simpler measures.

What a ridiculous description of BTMM. I don't think the original article author even knows what it is.... and I don't think but 3 or 4 posters on here even know what it is and ever used it.
Yes, you have your Finder sidebar with your home machine(s) showing for remote file access and screen sharing. You don't need BTMM for that on your LAN. But what was cool with BTMM is that with very little setup (totally easy), you could click on the home machine(s) in the sidebar from anywhere in the world (which I did) and get to the files residing on the remote home machine(s) and share the screen(s)... even if the remote access is behind a firewall that you don't have control over or leverages tethering (without NAT or UPnP it would be slow, though). The problem, however, is that I was successful in connecting maybe 80% of the time on the first usage (first since last reboot of home machine, since last voodoo dance ...who knows what condition...) and then maybe 20% or less of the time on second try (after network connection drops at local location or voluntarily disconnecting). As another poster mentioned, it becomes extremely frustrating because you end up sitting there in the hotel room or bar or whatever, thinking... "how can I reboot from here? maybe I can reboot router using BTMM (another nice BTMM feature when it works), but then that doesn't work either, so... fly home?
So I'm definitely bummed. I'd rather see it fixed (probably issues lie somewhere in MacOS) than dismantled.
