I just ran across a [link](https://askubuntu.com/questions/29445/how-does-gimp-compare-to-photoshop) to LMGTFY on Ask Ubuntu. In the past, I've [found it offensive](http://chat.stackexchange.com/transcript/201?m=376308#376308) when users have [posted](https://superuser.com/questions/67451/active-desktop-for-windows-7-vista/67529#67529) LMGTFY links for me.

When, if ever, is it acceptable to link to LMGTFY on Ask Ubuntu?
