I can answer this for you Mr P.
Hi there. This isn't actually my first post. You all know me originally as Tomiichi. The name change is just because I couldn't decide on an online alias, but I think I have settled with this one, Kataveryk. It's just a different spelling of "cadaveric" as in cadaveric material or specimens. I work with cadavers and am going to school to be an forensic pathologist, basically to do autopsies.
Going into answering your question, "why do people register and not post". I can tell you that I love booktalk. You don't know this, but I am on here every week. I try to read all the discussions, or at least most of them. My lack of posting is due to several issues.
1. I go to school and am holding down 4 jobs. No that's not a joke. I work for 2 companies with 2 jobs each. The jobs are not related to each other at each company so I literally have 4 jobs. 3 of my jobs actually have to do with cadavers, which I love. The 4th provides me with my benefits, which I don't want to do without. At the end of the day and/or week I don't have much time left and if I do I have to use it to study. So with my serious lack of time, I just can't spend more time on here.
2. Since I only get on once or twice a week, that leaves me with quite a bit new stuff to read through. So I try to pick and choose and I read through everything that seems interesting. Than before I know it time has slipped away and I have to log off.
3. With the time I have I like to spend it reading through the posts. You guys have already taught me so much just from spending time here. So I prefer to read everything instead of taking the time to post which actually takes a lot of time (like this post) trying to gather my thoughts. It's easier to just get on here and read. Does that make me a little lazy, yeah maybe.
4. I also don't get much of a chance to read other than for school, surf the web, or watch the news. So honestly I just don't know what's going on in this world enough in my opinion to post about it. I actually learn from you guys and these forums what's going on.
All in all, I love booktalk. I have been here for over a year now and I still get on at least every week. I wasn't always this busy, but this is where I find myself at this point in time.
I can't speak for the brand new people that have registered and REALLY never posted, but this is my answer. I will continue to be here in the background every week watching over you.
, I think I'm holding my own.
