There are so many great blogs out there, I love Openhelix blog, and many others already listed. But reading all blogs takes ages, though I have everything fed into my Google Reader.
That's the reason why last week we started our new community-based project biotricks.net, which is a meta-blog linking out to interesting tips, tricks, and tools for bioinformaticians but also hosts own articles, scripts, code lines, etc.
At the moment it is quite basic, but like BioStar it will become more interesting the more people are using it.
So please support and contribute to this project. Thanks.
