Other than google alerts...
I'd like to know anytime "StarStreet" "sports stock market" "starstreetsports.com" are mentioned. Anything out there I should be using in addition to google alerts?
Everyone personal or business should be using search.twitter.com. Think about periphery keywords (curiosity keywords), locations, emotions, etc (see advanced options) that may not directly create "marks" for you to engage with but more pull you into conversations that build your knowledge of landscape and the people moving with in it.
Of course there are plenty more which I look forward to seeing on this page.
I use www.samepoint.com and like it.
