I would love a function that enables multilingual blogging on WordPress.com.*
I believe many people who are blogging read blogs from all over the world, like me, and would like to be able to reach all of those people, too - to reciprocate, to analyze another blog post or write a response, or simply share content with them, without losing the possibility to reach friends at home, in their own language.
(As an aside, it even feels weird to comment on foreign blogs, linking to your website, and knowing most people who follow the link will not understand a word on it.)
It requires a lot of work to do translations, and not everyone is able to do so. On the other hand, for those who are able to and want to invest the time and effort, it can be a means not to limit their readership to their own country, especially if their first language is one not shared by many people - even if they do not have the knowledge or resources to blog on wordpress.org.
It seems almost anachronistic that inside the world wide web, there are still so many local barriers (even if only one-sided, for a part - I can read English blogs, but their authors and commentators cannot read mine). A multilingual blogging option could help to break down communication barriers between people from different countries. It could enable them to gain more readers, to share their thoughts with those who would like to know them instead of only those who speak the same first language.
*There are excellent plugins available with this function, e.g. qtranslate, but only for wordpress.org so far. (see http://codex.wordpress.org/Multilingual_WordPress). For WordPress.com, there are some rather complicated and unsatisfying workarounds.
The blog I need help with is kiturak.wordpress.com.
