Interesting free software for literature tracking by author names

I just discovered this neat free software tool for scientists by chance. It is called myPeers. It allow you to follow publications from scientists or authors you are interested to follow as their papers are indexed by Google Scholar. I suspect that for very up-to-date preprints or very new papers coming out, one might need to check out literature databases directly. However, if you are not too serious about getting the latest papers, then this tool could fulfill the job well.
