Stop in for a cup of coffee

Speaking of cashing in on your 401K, I know a few of you guys paly the stock market a bit. I have some squirreled away in savings that is only a 1% return. A couple CD's are at 1.3% and 2.15%. I think I could safely make more playing the markets a bit. You guys do it online? Has it been profitable for you? Rate of return?
