I want to state that I'm just giving some examples, among many factors. – John AssymptothMar 4 '11 at 15:57
Better to exclude "such as," since it doesn't contribute any useful information. – NeilMar 4 '11 at 15:58
Note that some style guides advise against using an incomplete sentence before a colon; that is, both what comes before the colon and what comes after should be grammatically independent sentences, which could theoretically stand on their own. They recommend either "many factors are to blame for this disaster: <list>", or "many factors are to blame for this disaster, such as these: <list>". Many others would say it doesn't matter, though. – CerberusMar 4 '11 at 16:03
"but not limited to" is worth its weight in gold when you are dealing with a group looking for someone to blame. Sometimes you have to stress that the list isn't complete. – user1579Mar 4 '11 at 17:33
