Every Friday, find five quick links about compelling technologies, emerging trends, and interesting ideas. Source: the internet.

1. Twitter quietly opened its analytics platform for general use. Now even small publishers can view and track follows, unfollows, and clicks to gauge performance of an account, and even download a CSV.
2. Facebook embraced the hashtag. This development has been greeted by many as the ultimate victory of advertisers over users. I agree with this Atlantic piece —  the pound sign doesn’t signal the apocalypse as much as a desire to engage users more through search and organized conversations and, yes, help those advertisers.
3. It can be tempting to rush to new technologies to pursue the grail rather than optimize what you have. This book excerpt details how the Obama campaign enjoyed success by optimizing a technology people love to declare dead — and by overcoming a dread of being annoying.
4. Kids like the handhelds and grownups like the tablets, according to Pew. Tablets  skew toward higher household incomes and educational attainment, but apparently there’s no significant difference in tablet ownership between men and women, or among different racial or ethnic groups.
5. Did you think it was only your preteen obsessed with Snapchat? Apparently it’s the summer of Snapchat for Wall Street bankers as well. Looks like the startup may have a shot at being worth the 100M round it’s rumored to be raising on a half-billion or so valuation.
