Google talk is an interesting little tool that could have many uses or none, but it is fun nevertheless. The theory behind it is that you type in three or four words, the tool searches for that phrase in Google, and then one word at a time, it removes the first word, and adds a new word. The results can be useful or meaningful or useless or meaningless, but they are usually interesting. What does any of this have to do with SEO? Possibly nothing, but then again, it may just spark some new ideas or new directions to take when targetting new keyword phrases. Or maybe, on a slow SEO news day, it is simply something to do.
