Here is what the list on part 1 contained:

• I would like to process this for a list of users. Done: Accepts a comma separated string of users whose tweets you want to read.

Function Get-TwitterStream{
##
#.SYNOPSIS
# Get the Twitter time line of a user or a set of users.
#.DESCRIPTION
# Get the Twitter time line of a user or a set of users using the REST API.
# 
# The api allows us to retrieve the timelines of users when queried:
# http://api.twitter.com/1/statuses/user_timeline.xml?screen_name=UserName
# 
# You can retrieve multiple pages but, for this script we only retrieve top
# twenty tweets in a single page.
# 
# Since, the function expects a string argument when passing multiple parameters
# you need to pass them as: "handle#1, handle#2, ...handle#n"
# 
#.PARAMETER TwitterHandle
# A user's "Twitter handle" is the username they have selected.
# 
#.EXAMPLE
# Get the Twitter timeline of a single user:
# Get-TwitterStream -TwitterHandle SqlChow
# 
#.EXAMPLE
# When getting the Twitter timeline of multiple users 
# Get-TwitterStream -TwitterHandle "SqlChow, BrentO, PaulRandal"

Much better to look at

You may ask why Powershell? The answer is quite simple. It is a well-established fact that PowerShell is a very powerful tool and there is no arguing that you could do ‘almost anything’ using it. Also, I love it.

There is a to do list

• I would’ve liked to throw in some more formatting but, since this was a proof of concept script I did not get it in. I would like to get back to this sometime in the near future get the output a little more readable.
• I would like to process this for a list of users, instead of the one user I process right now.
• Maybe put it in Perl using Mechanize…nah, just kidding
