Benefits from using different search facilities to search for resources? I'll go out on a limb and say that the amount of results showed would be different, their relevancy would also be sorted as according to their individual algorithms, and as such, we might get better sources from one search engines as compared to another.
Of course, I'm going out on a REALLY long limb here... I've never been very big on the whole compare-and-contrast thing, so my analysis of the benefits, strengths and weakness, of the search engines are rather lacking...
Site feeds? I'm not sure... I'd guess that, as with most things, I feel indifferent towards them. I'm not sure what site feeds are used for, other than to create a link to other websites. Would I use this in future? It's unlikely that I would ever need to deal with something like this in the future, so I'd say that I wouldn't be using the site feed thing soon...
Hmm...not too much to write about for this... I guess it's been a rather dull day today. That is not to say that the class wasn't interesting... It's just that I can't think of what else to write regarding this topic...
2nd Part
Hmm... I'd say that it is quite a bit more effective to search using the invisible web than using the search engines, but that will depend heavily on what the databases contain. Some may contain more relevant information about our research topic, while others may not contain a single scrap of information on the topic, relevant or not.
For example, my research topic is on the implications of legalising euthanasia and assisted suicide, so if were to search for any information on the ITPro database, nothing would turn up. My chances of finding relevant information would increase if I were to search in databases containing medical or legal information.
The advantage that search engines have over databases would be that search engines drag out any general information that they think is relevant to our research topic, while databases are very specific- a wrong word or a mistake in the phrasing would lead to information which may be completely irrelevant.
And yes, I would use the invisible web for research in my own diploma, because I will be studying for a Diploma in Game and Entertainment Technology, and there is a database that deals only with IT related stuff, and that would be http://library.books24x7.com/. Try searching for medical knowledge, though, and you would be better off sifting through the mess given by the search engines.
