Jon at the Clogger blog listed his five can’t-blog-without-’em tools, and invited a few of us to do the same. I WILL (belatedly) ACCEPT THIS CHALLENGE!
Hmm.
1. Blogger – I’ve used LiveJournal, and I have a MySpace page, but Blogger doesn’t have as much baggage. It’s pretty lo-fi but I can do whatever I want with it, and don’t have to fret over who’s on my “friends” list.
2. Flickr – Ah, sweet, sweet Flickr. How did I ever get along without you? Well, okay, I used to not have a digital camera, so I guess I got along without it just fine. And now I’ve broken mine, so I guess I’ll get along without it again. Nevertheless.
3. Google personalized home page –I keep a few core feeds up there for fast reference. Rob at Marketsync suggested to me the other day that this makes it too easy to ignore all the other feeds I should be reading. So maybe I’ll try his method for a while, and put everything in one aggregator.
4. Ma.gnolia – Like de.licio.us, but doesn’t make me unhappy when I use it.
5. Technorati –Though I’m sure I haven’t explored most of its possibilities.
And what do you, the reader, use?

I just use Delicious and a whole lot of mayo.
Don’t ask what for.
It’s not that you can’t use your Google Homepage … in fact, I just put all of my feeds into Google Reader and then put Google Reader on the homepage. Best of both worlds!
Basically, the reason why you’d want to do this is that by having things on your homepage and in your aggregator, you’ve unconsciously told yourself what’s important and what isn’t. By putting it all in once place, and preferrably a reader like Google’s that simply presents everything in a time-based stream, you have to give it all equal importance, making it harder to miss things.
