My LJ was imported to DW as of last September or so. I would cross-post if it worked the way I want it to, but it won't. Its great that you can set your DW up to automatically cross-post to LJ, but that's NOT what I want to do! I want to be able to update my LJ like I've always done (ok, technically not always, but for the last 8.5 years) and have it cross-post to DW. LJ is home, DW is the god-forbid something happens to LJ backup.
But... I've got a DW account set up (http://hellziggy.dreamwidth.org/) so I can still read anyone who moves completely over there.
If you are moving totally to DW & leaving LJ, let me know so I can add you to my DW reading list.
If you are moving to DW & cross-posting to LJ, but want all the comments at DW and are not having a link to the DW comments put in at the bottom of the LJ post, I also need to know so I can add you to my DW reading list.
If you're cross-posting and taking comments at either place, or your LJ posts contain a link to DW where you want the comments, I don't need to change anything with how I follow you.
I do check DW fairly regularly, but not as often as LJ, so I want to keep as much as I can on my reading list here at LJ instead of over there at DW.
