Twittume just got started towards building a resume using tweets. Short text/notes with hashtags, where hashtags are your skills. This way users can keep track of their skills and also add some context to how they have used that skill.
In a nutshell, users can keep track of their skills, accolades, and accomplishments.
What are we trying to accomplish?
Make resume building easier and painless. Also, make resume useful both for employees and employers.
