Sharing Time Together, Apart: Watch2Gether
And anything you can do that creates some kind of connection is worthwhile.
Which is why I'm so tickled by Watch2Gether.
It's a free service that lets you watch videos. But it's more than that, really. You can create rooms - temporary or permanent - and invite who you want to be in there with you. (Note that once you give out the URL of the room, though, people can pop in without an invitation.) But unlike a regular chat room, you can watch videos from a number of sources (YouTube, Vimeo, DailyMotion) together... at the same time.
Unlike some other options for this, you can have as many people as you like in there, and it doesn't require a specific browser or any addons. (It doesn't work on mobile, though...)
So, for example, you can get a playlist of videos from Alliteration Ink and put them in a room, and share the URL like so:
and watch the videos together. That particular room is moderated as well; only I can add videos and toggle playback, which is another nice feature.
So if you're separated from your friends, family, or other loved ones, this is a nice way you can do something really together while still apart.
