'Thankfully, 2K7 flows just as easily as 2K6 did. ' i dont get that what does it mean?

Answer 1

2k7 means the year 2007. 2k6 is 2006

Answer 2

It's written by an illiterate person. They're talking about the years 2006 and 2007 and trying to write it in a trendy way or whatever. But that's an incorrect use of the word "thankfully". It imples that the years are thankful! Don't waste time trying to decipher their point, because they're obviously an idiot.
