Been using this search engine on and off for several years now. Vast improvements have been made since then. Being a Web Designer, I appreciate seeing the front page of my site on the search engine, since I know how much time and effort goes into creating a great looking website. I believe they have a local cache system on their servers, the screenshots of the websites load very fast now as compared in the past. Advertising is very cost effective on this search engine as compared to others and CTR has been considerably higher. Most likely due to the Image of the actual site being there for potential customers to see.
