All of them are russian sites.
The first is Alex Exler's author's project - Exler.ru (RSS contains updates).
The second is Ilya Birman's blog - "Meanwhile" (RSS contains full posts, without images).
And the third is Weblinks.ru - 'interesting in the net' blog (RSS contains full posts, without images).
I hope these channels will be added, because they ought to be added.
Thank you for your attention.
