What is good about English is its punctuation. In Russian we have thousand idiotic rules which are learned for years...
And we have those who abuse punctuation here. Irosie for one example uses no punctuation at all. Then there's
2aguy who ends every phrase with an ellipsis (...). One can never tell if he's finished his thought, but judging from the content, he never has.
The one aspect of a Russian speaker that stands out for our eyes is the use of articles. I believe Russian doesn't have them but when they're not used in English we notice (above: "we have thousand idiotic rules" would be "we have
a thousand idiotic rules"). It doesn't prevent understanding but it does get noticed. Hope that helps.
I'll tell you one foreigner here whose English is perfect is
