I have made a blog aggregator in Yahoo Pipes to combine the blogs of multiple people who are taking part in the Seven Languages in Seven Weeks challenge.
There are easy links to add it to google reader, netvibes, bloglines etc.
I have also set up a twitter account that will tweet out the links to the blog posts.
http://twitter.com/sevenlanguages
If you’re taking part and blogging, let me know the URL and i’ll add your blog to the aggregation feed! :)
