In the fortune magazine, there is a section (and for the life of me.. I cannot seem to find it online and I just cleared my dining table of all the back issues of the magazine 🙁 ) on how business leaders see trends in real life and than make judgements on where the economy is headed. For example, if someone sees a starbucks they visit regularly become more busier than normal, that person judges that the economy is doing well.
I judge good talent (think sysadmin, dba, programmer, application engineer etc) in a somewhat similar fashion. I should note that this system is not perfect, but it seems to have worked out more than not for me so far. I judge their talent based on what browser and how they use it.
Ever see a person who has multiple browsers (not tabs) open and is doing a specialized task in each one of them? Their home screen is usually set to a specialized search engine (blekko, duckduckgo, wolframalpha) and they have add-ons that block ads and show them a variety of information of the site they visit. These are usually the best folks to have on your team. These are the folks that you want your systems designed by.
This group tends to either use firefox or chrome. Has Google as their home-page and know how to use multiple tabs. Yeah.. sorry, I a browser discriminator :). Since there can only be a few rock stars in the world, you should consider yourselves lucky if most of the members in your team belong to this group.
Ever see someone, whose homepage looks like Google but is not.. And has a bunch of “toolbars” that take up 1/3rd of the screen. And has popups showing up randomly? Yep.. these are the folks you don’t want touching your code. Even with a 10 foot pole.. no sir.. Having these folks move to firefox and/or chrome doesn’t help the situation either :).
