I don't think its a good idea to build your own dedicated server. for me i prefer to have my server on 3rd party hand and apart from that they provides you with the backup necessary to protect your data and server provider usually located in secure place so to build dedicated server on your own took a lot times and money spent.
I don't like some sites that actually makes a lot popups even after i closed it and usually this sites give me trojan and many other viruses but it doesnt affect me though he he
If we get paid by google then what google actually really earn from the advertising itself, it doesn't really makes sense isn't it. or we only get paid from highest paid ads?
