Feel free to "reblog" a link to the GIF, but it would be best to link to the containing page:

  http://www.viemu.com/a_vi_vim_graphical_cheat_sheet_tutorial.html

You can blog an image hotlinking to the cheatsheet inside a link that points to the containing page for best effect.

Also of possible interest, the "why vi" article:

  http://www.viemu.com/a-why-vi-vim.html

I'm the author of both.
