You could also try
www.fool.com - you can go through their articles w/o having to subscribe. If you are new to investing, invest in a Mutual Fund that tracks an index (they are called index funds). Watch the fees, index funds should be no-load, with fees below .5%
Pay close attention to fees - if you are buying a stock, the fee for the purchase should be less than 2% of the cost of the purchase (ie. if the commission is $10, you should buy at least $500 of the stock)
If you want to combine mutual funds with buying individual shares, try sharebuilder.com -
http://www.sharebuilder.com/AB/0206/V2/Index.asp this is a really good place to start.
Another thought is a process called DRiPing - dividend re-investment. You buy one share of a company that offers dividends and allows drips (morningstar.com can help here). A statement arrives that tells you the purchase price of the share you just bought and has a coupon that you send in with your next purchase. Generally there is not fee for this but sometimes there is a minimum purchase but you can get away with $10-50 each time. If you send in the minimum each time a coupon arrives, you will suddenly have a shit load of shares. I usually stop dripping when I get to 100 shares or enough shares the the dividend total buys a whole share.
Sorry, I did not mean to go into such detail. Good drip companies are KO (coke) and MMM (3 M) but I am not a in any way advising you to buy these stocks and accept no liability if you do.
I will answer any questions you have and/or point you in the right direction.
