[LinkedIn] Success stories through Twitter ...

It has been almost a month since my last article & once again busy schedule has distanced me away from my blog Few weeks back, there was an article on this blog about Twitter and since, than I have been much more active on it

Well, we all know about Twitter & it's usefulness for business. However, there has not been [at least I have not read about it] similar news like this one where startup/company has generated sales through Twitter.Below is the question that I have posted on LinkedIn and to answer it, you can leave a comment below or head-on directly to LinkedIn

There would be many more startups/companies [apart from Dell, Sun etc.] generating SALES through Twitter

Twitter, a company that is making news without making any revenue is familiar to all of us. Though, most of us on Twitter use it for personal use; I would like to know about the following:

1. Is your company/startup using Twitter ?
2. If the answer to (1) is yes, how have you used the medium e.g in generating sales, getting feedback ?
3. Is there any success story [apart from Dell making $1 Million in sales through Twitter] where a startup/company has been able to generate sales through Twitter.

PS - I posted this question after I could not gather much information from leading blogs/ websites/newspapers.
