like topcoder ,in codeforces we need detailed tutorial blogs not just editorials for contests ,

this community needs blogs like a blog specially on fft or on bipartite graph or simply on primality tests etc. by good coders .

i understand it is waste of time for writers but though it they can verify their knowledge about algos.

i request everybody to share knowledge on topics that they think they are good at(not here but in in separate blogs).

this will help the beginners (maybe some intermediates) and help community grow.

thx
