Not a yoyo IPO like Link'd InThe Russian Internet growth potential is huge. My personal opinion (and that is all it is) is the LinkedIn will slowly drift down to end up eventually in scarey territory due to lacck of growth potential. Yandex, on the other hand can both grow in users and ad revenues. Kind like Google vs My Space.
Hopefully both go up and stay up because I have a lot riding on the social media trend.
