There are many tech blogs lurking in the web, however- very few are established through many years of blogging and developing/hiring influential writers, niche topics and perseverance. I am going to list some of the best tech websites, and a small description as to what they are about and what type of content to expect.
The Verge: Non-stop tech news, product reviews and feature pieces.
Techcrunch: Breaking news and opinion pieces
Techmeme: News Aggregator
Mashable: Social media, entertainment and news
Businessinsider (SAI): Tabloid-format news
Wired: Science, tech and business oriented content
Pandodaily: Start-ups, Silicon Valley focused news and commentary
There are a lot more tech blogs out there, like Venturebeat- but these are the ones I read everyday because they all offer something different in terms of editorial.
