Say you run across a really cool webpage that you want to share with all your friends and a few thousand other people? You might submit it to Digg, Reddit, and maybe even another service or two before you run out of steam and enthusiasm.

Social Poster makes it easy to submit links to 34 different sites with just a few clicks. You can grab Firefox toolbar button by going to Social Poster's main site. Now visit any web page, highlight some text and click the SocialPoster.com button.

You'll see a new page with the URL, title, and text you've selected. Social Poster even generates tags based on the content of the page. You can edit any field before posting. On the left side of the page are 34 social bookmarking sites, including Digg, Netscape, Reddit, Del.icio.us, Stumbleupon, and a few dozen others. Click the Post button next to each site and Social Poster will fill out most of the information for you.

You'll still need to have an account with each service you submit stories to. But Social Poster can save tech evangelists (or web site promoters) a lot of time and energy.
