Okay, I'll admit it.  I'm addicted to MicroBlogging, Twitter especially (though I have some fondness for Pownce as well).  I just can't get enough of it.  A year ago I stated "Twitter is for Headslappers!"  Well, I guess I'm a headslapper, cause I can't go more than a few hours without checking my Twitter Feed.  I use a desktop client, Twhirl, to keep track of it on a regular basis when I'm home, and I have a link to Twitter on my home screen on the iPod Touch, so if WiFi is accessible I can check Twitter (though I do check my email first.  Priorities.  Email can make me money.  Twitter hasn't done that for me, yet.)

Another addictive web app for me is Google Analytics.  I have a desktop client for that as well.  I just love checking the stats on visitors to my tech blog.  It doesn't change the way I blog, but it has made me more conscious of what can draw traffic to my blog, and what doesn't work well.  (I've had little success using Digg to get people to my site.  Reddit hasn't worked at all.  Stumbleupon pumps traffic to my site at an astonishing rate at times.)

But the most addictive thing I do on the web:  Google Hosted Domains.  I love the fact that I have this huge GMail box, but on my own domain (dogboi.info).  I can have up to 100 email addresses there for free (not that I'd ever need that many.)  Plus, I get Google Calendar, Google Apps, etc, all on my domain.  Sweet, and it's free.    

And if you are using Twitter or Pownce and want to add me there, my screen name on both is dogboi

Just send me a message on whichever service telling me you're adding me because of livejournal.  :-)
