Ninite.com has a list of excellent free software that you can install with one click. When setting up a new computer it can save you hours of time.
I use Chrome, Firefox, iTunes, VLC, Audacity, Spotify, GIMP, OpenOffice, CutePDF, AVG, Spybot, uTorrent, Dropbox, Steam, Everything search, ImgBurn, 7zip, Eclipse, and Python. All of these can be installed with practically zero effort and no extra crap, just waiting for the download and install to finish.
It suddenly occurred to me that not everyone uses a website I love. Of all the websites I browse if you asked me which one improves my standard of living in the largest, most concrete way, it would be slickdeals.
What it is: a community driven "hot deals" website with voting. By itself this is already useful, but the best feature is deal alerts. you never have to actually browse slickdeals. Just create an account, set up deal alerts for whatever strings interest you (I for example have a deal alert for "whey" to get alerted to deals on whey protein powder).
More than 50% of my belongings come from sales I've been alerted to via slickdeals. Any big ticket items I need, but don't need immediately I just set alerts and wait. My laptop, desktop, tablet, smartphone, clothes, toiletries, books, games, even some food are all slightly better for the price I paid than they otherwise would have been.
So what other sites am I missing out on that would make my life a lot better?
A website I just discovered for habit building chains.cc seems cool, but I haven't had time to evaluate its usefulness yet.
