Well, despite my copy being fairly out of date, Twitter for Dummies was actually informative - a nice surprise. What's interesting about Twitter, as the authors point out, is that there's so much variety in the third party applications available that you can never know about all of them.
It was also interesting to see what people were saying about services like Bit.ly and Dropbox back in 2009 - the authors gave the then-fledgling services a glowing review and predicted great things for them in the future. It's now the future, and they're both doing great things.
Also interesting was a mention of Ari Herzog, a digital marketer who contributed his opinion when the authors were carrying out research over Twitter - I've recently written a guest-post for his blog, and so it was cool to come across him in the manuscript.
It's weird how, in the world of social media, everyone is interconnected - I can generally tell whether a social media book is going to be worth reading if I've heard of the authors in advance. I must admit, I'd never heard of any of the three authors beforehand, but I'll be keeping my eye on Laura in particular - at the time of the book's creation, she was working on a new site called OneForty.com, a site which I was familiar with. While writing this review, I did a bit of stalking, and I discovered that Laura now works for HubSpot. Cool!
