I'm hoping someone closer to the WolframAlpha team and work can shed some light on this - but is the extensive use of the first person warranted here? There's an awful lot of "I" and "I've".
Is the work being done really so directly attributable to Stephen Wolfram or is there a army of hard working individuals behind the scenes not being referenced here? I'm not suggesting they list everyone by name or anything, but a simple shift to something like "our team" would seem more generous. Of course this is all moot if he is indeed primarily or almost solely responsible for the progress being referenced.
