Tweetmeme-The tweet aggregator

Tweetmeme has several uses.  You can retweet the most popular tweets, find content, and post content.  How do you post?  Add a button to your site.  Users can comment on stories, tweet story comments, and promote your own original content. 

Twtpoll-Do you wanna take a survey?

I got thrown back to my college years when I first saw this site.  I remember surveying people in person and hating it because of shyness.  Now, I can ask unlimited questions, get 400 responses, get Twitter and Facebook comments and embed a widget on my blog, all for free.  I'm a huge fan of the free and as a casual user, Twtpoll is a great tool.  Even if I were someone who needed more features, a one time fee of $89 max for polls and $249 max for surveys isn't bad. Add branding with your personal Twitter handle and this site is golden. Did I mention it's a one-time fee...FOREVER.  For agencies who manage multiple accounts, $79- $129/month isn't bad.

Now that it belongs to AOL and has a Twitter exec in charge of social impact, the Huffington Post has a new channel.  Using CauseCast and Causecast nonprofits, they're highlighting good deeds around the country and nonprofits that are helping people, the environment and animals. 

Blog Grader

Don't judge me yet.  I just started.  Blog Grader judges blogs for content, relevance and followers.  It's like Google Analytics, but solely for blogs.  Their company also makes Twitter Grader, a rival to Twitalyzer. How relevant are you?
