While sometimes they can be, generally they tend to be google bots* or msn bots* or the like.
*these bots are automated computer programs that run around the internet looking at a lot of websites so that when you type your query into google or some other search engine, you get relevant results.
Thanks Brett, lets wish they were real guests, then I wont feel so silly talking to a ‘bot’. Yes I am computer illiterate so am proud of the fact that I’ve even worked out how to do this. I thought I was brave even trying.
