A few comments: - the tagging tool doesn't work well, tried Senior System Administrator, didn't find category, same for CTO - I tried "CTO at companyx, Montreal, Canada" it showed "text too short" - you might wanna also weigh in the number of followers to rank the tweets. I think a twitter bot will have less interesting tweets (auto-generated tweets), while a company's official twitter account will have much more followers, with legitimate twitter jobs - you should also have a navigation menu, or search function to find jobs by city or country

also I'm ok with using the hashtag rtjobs, but #jobs is more obvious no??
