You already understand this if you work in an office which has no internet filter, and also has a lot of people who use instant messaging of any kind. I wouldn’t call link sending an art per se, but there’s definitely a right and wrong way to do it. This is about a friend I have at work (now I’ll know if you read my comic or not) who loves sending links to everyone he’s friends with at the office.

Problem is that he doesn’t always look at them before sending them out, or sends them to people who end up having no interest in them. When I send links I know the person I’m sending them to will enjoy them and/or it won’t take up too much of their time. Sending a nearly ten minute movie clip is not a good idea. Sending a picture of a REALLY CUTE cat however is (assuming they like cats).
