Language Fileter in Twitter (or in Facebook)

Nowadays, SNS connect many people around the world...
I use facebook, twitter, and mixi (that is Japanese domestic SNS)

I don't know about the others, but for me, the SNS has some target friend.

Twitter is more like for Friends in my Japanese university,
and mixi is for my high school student...
As for facebook, it is more general, now it is getting for everybody, but for me, it used to be for the people whom i met in abroad

I might mention about my idea how to integrate these, or how to make it easy to do "targeting" in the same sns in the future.

But today,  i will say, or complain about twitter or facebook.
In twitter now i have approximately 90 followers, including japanese, american, and french.

One thing that I feel so sorry is my tweets are almost in Japanese, and sometimes English.
then... of course, it must be really annoying to have the TL all in unknown language for my friends! but as the ones are my friends, so they cant un-follow me...
Or even for me in Facebook, i have a lot of foreign countries friends, korea, thai, france, america, morocco...
sometimes i feel not so good when my news feed is filled with unknown language...
if its include picture, then it is ok though

then, what if we could have language filter??? like "show only French" or "show only Japanese and English" maybe google translate is able to recognize what the language is, so... technically, it is possible i think :)
