I love reading blogs, because you never know what you will find. I'll try a new blog, and if I really like it and I am not too distracted, I will usually put it into my favorites list. But what usually happens is that I read a few posts, glance at the links list, and say to myself, "Hey, that looks interesting!" and click away. Without virtual bread crumbs, I usually can't remember that really interesting blog on x-topic, because I've already lost my way in the blogosphere.
That is why I really like bloggers who link to others. Even if I can't remember where I saw something, if I go to certain bloggers I have a chance of finding it again.
For Jewish blogs, Haveil-Havalim is of course the best place. Organized by SoccerDad, it is published once a week. You can find out where here.
Ezzi at Serandez posts a blogger roundup, in case you don't want to wait for Haveil-Havelim. (Where does he get the time?)
TelChaiNation links to a ton of people in his posts. What I also like about his site is what I think is the best organized links list I have ever seen.
And for those of you looking for a new place to register your blog, check out Jewishnet. I found it on the DryBones links list.
Happy blogging! And if anyone comes up with some virtual bread crumbs, I'm in the market!
