I've a blog site. I want to add Twitter status update script in my blog. How can I set up it. Please help me!
It seems that you want to populate your recent blog posts to your twitter. If so, you do not need to code or implement anything. Just grab the RSS feed of your blog and use it with dlvr.it website which is a free service. If you are looking for anything else, please elaborate your problem.
What type of blog are you running? What plugins have you already tried that you didn't like (save us suggesting the same ones over and over).
