Like if you think the Ukrainian courses are AWESOME!
I was really looking forward to learning a language in the cyrllic alphabet like Polish or Russian. But ukrainian has really caught my eye. Who likes it?
I come from a Ukrainian family, but all of my Ukrainian speaking relatives are dead or I've never met them. I went to Ukrainian school as a kid and learned some really basic stuff. What is in the DL course seems to differ from what I learned. Just enough to make me raise my eyebrow...
And by the by, Polish is most definitely does not use the cyrillic alphabet.
I'm learning Ukrainian and Russian at the same time. Almost every phrase in Ukrainian I learn, I try to find the Russian equivalent. I've been using GoSpeaky to find skype partners, and if you're an english speaker, you'll be amazed at how many Russians and Ukrainians will contact you wanting to learn english.
I've been studying polish on and off for 10 years, and have studied a bit of Serbian/Croatian. So learning Ukrainian and Russian is not as difficult for me. They share many similar vocabularies so it's like learning spanish and italian at the same time. If you don't have experience keeping languages separate, you might mix them up.
