At times I wanted to push some files with my blog so that people can download and check something locally. Up until now, it was not a straight-forward way. I either uploaded the file to my own server or google pages or somewhere. Then linked it on the blog.
However, you can now publish files from Windows Live SkyDrive (total free space of 25 GB) or Google Docs (Total free space 1GB). If you haven't checked already, google now offers you the opportunity to upload any kind of file without conversion. I know there are other services like this, but these two should be reliable.
I took some information from this Tim Anderson's ITWriting blog.
