It looks very Professional to me.Though most of what you are talking about is mostly GREEK to me.I know only basics about most of those things,so this could be very useful to me especially.It is great to see that even though I don't know much about those things,you are still not looking at me like I am dumb.You seem to put it to people like me..like...Your not stupid,you just need help.Thank you for that too.
The colors seem to go together very well,and don't hurt my eyes to look at for awhile.I see that alot with some sites.It also seemed pretty easy to get around the site too.Really user friendly.
It all comes down to this.....when I need to learn how to do something or better ways to do them......I will probably look there to see if you have something on it.At least one of my first 5 choices.
Probably the top 2 really..lol.
Good looking site.
