In the spirit of Makeuseof.com's list of Cool Websites and Tools they publish daily, I'd like to share a list of resources, as I come across them, that I find useful:

• Xenu's Link Sleuth - small, fast Windows application to test your (or any) website for broken links

• Builtwith.com - similar to Sitonomy.com; tells you about the underlying technologies running any website

I just learned yesterday that Windows Live SkyDrive offers 25 GB online storage free!  That's a lot of free storage.  And then there are the other two similar but distinct products Microsoft offers: Live Sync and Live Mesh.  Here's the breakdown:

• SkyDrive - an online backup utility.  You can access it via the web interface or you can integrate it into your Windows environment with SkyDrive Explorer.  Again, 25 GB is a lot of free space!

• Live Sync - lets you synchronize files between several computers.  The difference between this and the other services is your data doesn't get saved online.  If you want live synchronization between computers and online backup, there's Live Mesh for that.

• Live Mesh - similar to Dropbox, but offers 5 GB free space instead of Dropbox's 2 GB.  I haven't tried it yet, but it seems to offer some other features as well, like remote control of your desktop.  I've been using Dropbox for over a year.  It does what it does very well, so I see no reason to switch.

Obviously there are other, non-Microsoft, offerings out there, but I wanted to focus on these because initially I was confused why they have three different services that do the same or similar things.  Here's a more detailed comparison of the three offerings listed above.

Update

I'm impressed with Woopra as well.  I was using the web interface for a while but decided to download the desktop client.  It offers more features, like filters and such, but the Exclude Visits feature seems buggy.  I entered my own IP address to be excluded from the visits but it still shows up.  Apparently it's a problem they're working on fixing.

The only other shortcoming I can think of is the lack of organized documentation for Woopra, the way there is for Google Analytics.  The only source for solutions and answers is the forums, which are great but, in my opinion, should be a secondary source, after official documentation.

So far I'm impressed with Clicky, although I haven't had a chance to test out the Spy feature which shows you real-time activity as it's happening.  On the other hand, Piwik doesn't seem to be collecting data.  I wondered if it's the WordPress and Joomla plugins I used, so I implemented the raw code on another site, but still no results.  I can't tell what's up.

I'm also giving Woopra a try.

I'm giving Clicky Web Analytics and Piwik a try.  I use Google Analytics right now, but even though it's very powerful, it's not the most intuitive (read: simple) interface to get around.  I want to try something else.

For Joomla integration I'm using the RokClicky for Clicky and Piwik analytics plugin for Piwik.

Clicky is web-accessible like Google Analytics, whereas Piwik has to be installed locally.

DO NOT DO BUSINESS WITH SOFT COMMONS and/or JOHN SHIPP

I did some work for this person without any payment up-front, on the basis of faith (my own stupidity), and he has yet to pay me for it.  He e-mailed me to invoice him, which I did, and after that he stopped responding to my e-mails and calls.  The sites I worked for him on are ClubKicks.com (PHP) and Five Nines Group (JavaScript and image-editing).

I tried to report him to the BBB but realized I don't even have a mailing address for him.  Had I been smarter I would have noticed that neither of his websites list a mailing address, which is not the sign of a legitimate business.

So do yourself a favor and stay away from this individual.  He is not reliable or trustworthy.  It has been well over a month since I invoiced him, and I have repeatedly communicated to him via e-mail and phone, to no avail.

He is based in Nebraska, out of Lincoln I believe.
