Watch That Post!
A simple Python script to "watch" a post. I wrote this to
watch posts on LiveJournal, but actually you can use it
to watch any URL.

To use the script:
1. Create a file (e.g., urls.txt) and add the URLs
you want to watch - each URL on a new line.
2. Change the variable period to whatever seconds
you want to let the script sleep.
3. Run the program: python watch.py
