Data Mining and Research

I need the below Google Docs spreadsheet filled in as much as possible from a list of names. We are looking for all names to be researched, some only have first name therefore no information can be found therefore it will be less then the 228 on the list.

Research for each person on LinkedIn, GitHub.com, Twitter etc is required. To find github accounts it's best to go to google.com and type in the search box the following to find the persons account:

github name-of-person

If you find the person on LinkedIn you can click on the contact info button underneath their image to find more links and contact information. You can also find links from their github webpage. If any details cannot been found for the individual on the internet then the field can be left blank. Deadline is ASAP. If the job is done well and quickly there is lots more work.
