One multi lingual post is really not practical for readers, actually, when the posts are that long.
I did that for a while, with in-page linking that works fine on peakd. The reasons i stopped doing it are mostly real life related, but also the lot of work to do it, for nearly 'no appreciation'.
Anyhow, you can check one of mine to see how i've linked the different languages there. If ever you're interested of doing so, i can find some time to explain/show you these how-2's.
