Theres definitely pleanty of influencers missing from the current set, McCarthy, Hoare, Dijkstra, to name few. If this were my list, I wouldnt have Lovelace or Gates on it, but most of the others seem warrented enough (in my opinion of course) :)
The persons you name are of course on the list. Lovelace already visible the others will appear in the future. So every day one person is added.
If you have other persons you want to see on the list you can submit person with a link in the footer of the page.
The rest generally applies.

As far as BASIC goes it was designed in 64 at Dartmought College (http://www.jake.dk/programmering/qbasic/dk/historien.html). I think Gates did develop a dialect of it though...
It's not a best of or top 100 list or something, it is in random order. But Tim Berners Lee is of course on my list, so he will show up in the future.
It is similar to the Erdös number.

But please don't redirect giantsofit.org to your current feature, it makes it tedious to correctly bookmark, and share, the site. Minor but unnecessary annoyance.
