I'm not shy, and don't worry if people turn me down. I always find any opportunity to 'show off' my languages - Guten Tag, Ciao, ko ni chi wa, Salaam... even I just knew a few words of their languages.
I made some friends with native speakers of English online, and they were very willing to help me with my English online before. One of them was very very very wonderful.
However, I prefer forums. Mostly I focus on my writing than my speaking.
