On a travel and lifestyle site I described Twitter this way: Twitter has a high barrier to entry and if you don't put in the time to figure out how best to use it, it just might be worthless.

For me it's a revelation and has absolutely changed my life in the year I've been using it for mindcasting. I'm now the #3 Twitterer in Istanbul!

I've virtually attended conferences around the world, gone to business school, gotten up to speed on my industry, and find invaluable the opportunity to connect trending thought across a slew of fields, learning and engaging alongside the top thinkers in innovation, healing, social media, sustainability, you name it.

If you're an intellectual Twitter is fabulous.
