As for the bandwidth conservation and ease of use… commenting remains a big hassle these days as it forces you to leave the sane and simple world of aggregators. (plus of course that some people like to annoy others by requiring registration… ;)

Personally I like the bilingual idea. Unfortunately my French has gotten rather bad in the past years. What I found particularly difficult about your French posts in the past is that they were mostly about films. Cultural topics just seem to require a much richer language to be written (and understood), making those post doubly difficult for me. Probably much more difficult than writing about more technical things. (I can see good reasons for splitting things the way you do, but it makes things harder – for me at least.)
