Yes you can use Twitter for SEO. But an effective Twitter account does not just help in SEO.
Twitter is good when it comes to communicating with your clients. Lately, Google is planning to rank Twitter links on search results. So, I think being active in Twitter will somehow help you rank your site.
I think that it is....but you should use your twitter account smartly. There might be a time when you post your tweets in an off time, then you will get no results. For the best and most effective result you should post your tweets in peak times and there are apps that will help you do that.
Update for 2015:
I see this post has been around for about a year now so I figure I'll update it. Twitter and all the other social media sites no use "do-not-follow" tags for links. This means that they won't help your SEO when it comes to giving your site meaningful referances.
Where they can help still is by giving you traffic to your site. When the search engines see more people coming to your site (and hopefully staying on your site with your excellent relevant content) they will reward you by giving your search results more weight.
Best of luck!
