With havin so much written content do you ever run into any problems of plagorism or copyright infringement?
My site has a lot of unique content I've either authored myself or outsourced but it looks like a lot of it is popping it up all over the web without my authorization. Do you know any techniques to help reduce content from being stolen? I'd genuinely appreciate it.

Superb blog! Do you have any suggestions for aspiring writers?
I'm hoping to start my own site soon but I'm a little
lost on everything. Would you suggest starting with a
free platform like Wordpress or go for a paid option?

There are so many choices out there that I'm totally overwhelmed .. Any tips? Thanks a lot!

First off I want to say superb blog! I had a quick question that I'd like to ask if you don't mind.
I was curious to know how you center yourself and clear your thoughts prior to writing.

I have had difficulty clearing my mind in getting my ideas out there.
I do enjoy writing however it just seems like the first 10 to 15
minutes are generally lost just trying to
figure out how to begin. Any recommendations or hints? Many thanks!

out. By the way I've bookmarked your site: http://www.blogger.com/comment.g?blogID=8824355573054493115&postID=8706825519279969718 and will certainly be visiting frequently. Many thanks!

Hi just stumbled upon your blog from Yahoo after I entered in, "Blogger: Belajar Ilmu Komputer" or something similar (can't quite remember exactly). Anyways, I'm delighted I found it
because your subject material is exactly what I'm searching for (writing a university paper) and I hope you don't
mind if I collect some information from here and I will of course credit you as
the source. Thanks.

I know this if off topic but I'm looking into starting my own weblog and was wondering what all is required to get setup? I'm assuming having a blog like yours would cost
a pretty penny? I'm not very internet smart so I'm not 100% certain. Any recommendations or advice would be greatly appreciated. Cheers
