I originally used Skype for video and MSN for text chatting, but once Skype gobbled up MSN, I got put off using it since there are many times I’d prefer not being online for voice/video chatting.
What I really miss from MSN is custom emotions. Sure, there were some users that went overboard with them, but I personally found it made using MSN far more enjoyable, especially with creative use of them.
The following is a random example where MSN was open in a screenshot I took several years ago, in this case about a new espresso maker:
To give another example - although Kate Perry’s music video Roar (link) didn’t use an actual IM app (if it is, please mention), I’m sure it wouldn’t be quite the same had it been done with a Skype app.
Another feature I use to like with MSN was ability to send pictures, especially the earlier versions which made it easy to send huge attachments that were too big for e-mail and didn’t involve a tedious web based file sending service.
If anyone is using an alternative to Skype/MSN that supports custom emotions or file transfers, please mention it here.
