Be aware that you now have mechanisms to write to and read from the internet. Plus you have mechanisms to read to and write from the serial port. In other words, you now have the beginnings of two-way communication between your Arduino and the internet.
Some people have used this to connect their Arduinos to internet time servers, periodically connecting and reading the internet time from an NTP server then displaying it on a local LCD. Some people have LCD news tickers. Some people read their web-site and ring a local bell whenever their hit counters are incremented.
The ideas are limitless.
Bon chance.
