Until the
Facebook/Twitter cross-posting feature was released, I did not bother to go to DW to comment, even if comments were only accepted on the person's DW blog. Now, though, I use my LJ identity via OpenID to read and comment on DW.
I changed my mind after the new cross-posting feature finally convinced me to set up
a Wordpress blog in my own domain. I figure that if I am going to pay to blog publicly, I may as well do it in my own domain, on my own terms. I intend to have all of my blogging migrated to that blog by the time my paid account expires in January. But I will keep my LJ account here just for reading/commenting on blogs that aren't anywhere else.
If you have a Dreamwidth blog you want me to subscribe to, let me know.
