Last week, I received some tips of Google offering spelling suggestions in Google Suggest. Google Suggest is basically the suggestions given to you as you type your search query in the Google Search box. At first, I honestly didn't know if it was new. So I emailed Google and never received a response, which is unlike Google.
But Google did blog about it over the weekend and I now know it is indeed new.
