#2A note from near the bottom:
For the benefit of readers who aren’t necessarily Go players, a four stone handicap means that black (the computer) was allowed to place four stones on the board before white (Ishida) made any moves. This may sound like a lot but, while it is a significant handicap, it’s not really as big as it sounds.

In my estimation (I play go), beating Ishida Yoshio at 4 stones in a non-simul game [1] probably requires a player that's at least 4 dan amateur.
[1] Professionals usually play amateurs simultaneous games. That is, 1 vs. many. The quality of play improves dramatically if they are playing a single game. In this case, a single game Ishida probably wanted to win.

yeah; there are some people in the comments suggesting that that Ishida might not be playing at the level of a top 9p right now, but this is still pretty significant and a very impressive feat.

Yep. The difference between Ishida and a top pro today probably isn't more than 2 stones.

That AI is 6d on KGS.

#7On a semi-unrelated note, is there a decent English-speaking online Go community anywhere?
I would like to try my hand at playing but I can't find anything along the lines of FICS, or even a decent-looking client for Android.

www.gokgs.com is the server that's probably biggest in the English speaking world. The desktop client is Java based, there is an Android client, and we're waiting for an HTML client (it's in closed Alpha). There are several other servers that cater more to Asian players, but you can certainly play on them.
There is also online-go.com, which is web-based. It has real-time games, but the majority of games on the server are correspondance.
Resources: senseis.xmp.net (an old wiki that has lots of content, but few active contributors), and lifein19x19.com/forum, a forum dedicated to Go.

KGS is the usual recommendation. Also check out Sensei's library as a learning resource.

Even that is probably high. I think any professional in the world could lose on 5 stones (c.f. http://www.computer-go.info/h-c/index.html).
