My list is so long that I'm sometimes forced to skim just to be able to read it all, and I don't like doing that. I think every post deserves my full attention. So I need to cut it back again. If you were dropped, it may be because you haven't posted in a really long time. Or it could be one of or a combination of the following two reasons:
1. You don't comment or haven't in a long time, so I assume you aren't getting anything out of reading my journal either as a source of thought provoking ideas, a view of life from a different perspective, an opportunity to debate philosophies or simply as a source of entertainment.
2. I either am unable to relate to what you write about or simply don't feel I'm fully appreciating or benefiting from your unique perspective.
It should be noted that you are not required to drop me just because I dropped you. If I didn't want folks I don't know to read my LJ, I wouldn't be making 1/3 to 1/2 of my posts open to the public. In fact, I recently (accidentally) discovered how to make public posts that show up in your journal for non-friends or non-LJ members to see but does not show up on my friend's friends list when they are reading their friend's posts. This particular post had a counter on it, revealing that at least 50 people that don't have me on their friends list are reading my LJ. I can't imagine why so many people would read it without adding it, you're certainly welcome to do so (as long as you're not offended if I don't add you back for some reason).
