I have too many journals, let's face it: There's my heart-health journal, with which I've become bored; it's served its purpose, and I'll probably delete it, although I'll do an occasional entry here letting you know whether we're maintaining, losing, or gaining weight. Then I have my memory journal. I like it, and I'll probably leave it there even if I seldom update it.
This has been my main place for blogging, and it's served the purpose just fine.
Trouble is, I don't have a lot of confidence in AOL being around forever; if they were losing money when people paid to have them, how are they going to stay solvent by giving away their service? That's why I started my latest journal on Blogspot. I didn't want to make the same entries in that one as I do here, so I'm more or less alternating between this one and the new one.
The only reason I don't leave this one alone entirely is that I know once I leave J-land, I will lose some long-time readers. Some people find it difficult to go anywhere else to read journals, and I've seen a few people take it as a down-right personal offense when folks move to Blogspot!
So, there's your explanation.
