I did this for a while. A few comments. First, as pointed out by pwg, you might have a dynamic IP address. Also, your ISP may block access to port 80, but there may be ways around that (not sure anymore). Second, I had occasional "brown outs" that cut the power to the server, so my website would go down at weird hours a few times per week. I purchased an uninterruptable power supply, which fixed that nuisance. Third, I had a small user base (no more than ~5 people accessing the site at any one time), so I had no problems handling the traffic.
