I'm product manager for Yandex Blog Search, russian blog search engine.
We have some difficulties with LJ.
Main difficulty now is that any community, for example, http://lj-dev.livejournal.com/ (and http://lj-dev.livejournal.com/data/rss) is not a redirect to right location (http://community.livejournal.com/lj_dev/), but a duplicate. It leads to some side effects in our blog search.
Do you think it is bug? We reported it first day after URLs changed, but it was not fixed.
Sorry if this is wrong place for such questions.
