BETA IS EVIL!
I started this post the other day but then deleted it, thinking all would be well with Beta Blogger once I understood what was going on. But the more I think of it, and the more I read of others' problems, I realize this isn't just my problem.
At first, I thought it was something personal, that certain people had blocked me from commenting, and I was a little concerned that maybe I had said something that had ticked them off. But then after reading Iron Pol's post about the problem, I realized it wasn't just me.
I can still comment on others' blogs, but now I have to use my login name (which, since I was in a hurry when I started the blog, and I am typically unimaginative and clever in thinking up a good name, I put my own name down). I would rather use something clever or more anonymous than my own name, so I might have to change that--if I take the time to figure it out.
I considered switching over to Beta, just because the promotional info every time I logged in popped up, enticing me to make a switch and have a better blog. I did attempt to do this, but once I got into the actual nuts and bolts of the instructions, I decided I didn't have time to figure it out.
I type and read fast, the only reason I really have time to do any blogging, but I have never taken the time in depth to figure out all the clever and fancy stuff like others have on their blogs. So it is just a stripped down, plain and simple, version for me.
Something I read did say that eventually Blogger would change things so there was compatibility again, but in the meantime, and until Blogger forces the issue, I will continue the way things are and log in to make comments on others' blogs as myself. I hope this answers others' questions as well about the Beta mystery.
