^ thats right. i had read about the akamai CDN thing but forgot/was unable to post immediately for mrintech's benefit
even the apps they use are their own (whatever is available), so yes, word, excel too. for stuff like employee time/labor tracking they use(d) a thirdparty tool but were planning to build something in-house (not sure of current status).
for intranet apps like HRweb and other internal websites they used to do ASP.NET and all but now they are heavily into "MOSS" (ms office sharepoint services) and their "SharePoint" product (last i know) which was supposed to get all fancy wiki/cms type features - dont know the latest status though...
some occasions they dont use their consumer apps rather in-house tools built with the underlying components, for example, by reading blogs i understand the devs use some sort of custom tool which uses the visual studio underlying compilers but not the visual studio UI itself...
i wonder what happened to apps like InfoPath - it was supposed to be the next best thing since sliced bread.
