Here's a cool site with a variety of Twitter Buttons that you can easily get the code for to add to your website or blog as another means for people to find and follow you on Twitter.
For those that are using wordpress for your blog, there is a plugin called "sociable" that will allow you to linkback to any of 30 social media sites from your post. Just look for the "sociable" wordpress plugin in google and install it. You can change the settings to include twitter, facebook, technorati, and 30 more!
I don't have the Twitter Feed installed on my wordpress direct blog but I have just installed it and it seems to worked OK for me. Do you have flash 9 installed?
Kittie,
Did you use ftp to install it? Sorry for the ignorance of my question but that is the only way I know how to upload and install things on websites (without the cPanel of course).
