I am horrible at Cs:s surfing, I always fall off of the ramps and end up in the jail cell things. I still cant figure out what the point of the game is and why anybody would want to play it. Some of the surf maps are so confusing! There is often hidden doors and phones involved in the maps. (surf_matrix)
I play Cs source, the newest release. Since the servers use Valve Vac 2 anti-hack technology hacking isnt the biggest problem even though client side hacks (e.g. inivible walls,no-smoke,aim bot, ect.) Cant be caught by the server unless it runs a consistency check. In CSS you have to do a hack just to get into a console. Normally you can just push delete or insert.
Yes, I use google site maps and i find it to be very helpful. 1. Your site gets indexed very fast, 2. You can see live stats on how your site is doing. 3. If you make any updates, just re-submit your sitemap and you get re-crawled withing 24 hours. I find it very helpful and i would suggest everyone to use it.
