I imagine that more than 50% of the WotC community play nothing but M:tG exclusively. WotC also encompasses the Avalon Hill forums.
That is a good point, and one (with my D&D blinkers on) that I hadn't considered...
So looking at the official "product" groups, I can't see one for Avalon Hill or the Star Wars RPG (or any other WotC "products" for that matter). There appear to be 2 product related ones - D&D at just under 700 members and MTG at under 400 - I'm assuming no-one was automatically signed up for them. Looking at the various other regional and fan created groups, it seems like the ratio of just under 2:1 for D&D:MTG seems to be reasonably accurate.
So if we assume that 700/1100 = ~63% of the board members are interested in D&D, then that still means the DDI subscriber base is 8000/(63% x 174000) or just over 7%. A slightly better number, but still not huge...
Although I think WotC execs would be content (if not overly excited) with 10% of the possible market being signed on to DDI, and if we assume that there are are number of subscribers (~2000-3000) not reflected in the DDI group then they're probably close to that mark.

One of the problems that may be contributing to this is that a lot of the crunch books have needed a lot of errata, so the DDI sources are BETTER sources for this information than even the PRINT BOOKs.
That's certainly part of the attraction. In my games, the character builder is usually considered a more correct source than the printed books exactly because it incorporates errata. However I don't think it's the full picture. I think other contributing factors are:
- 4e (especially when played with power cards, which are generated by the character builder as default) lends itself to being played without referencing books at the table.
- Most 4e books are crunch heavy and don't lend themselves to being casually read away from the table.
Those two factors, combined with the ease of incorporating errata make purchasing 4e books a lot less attractive than prior edition books, if you're a DDI subscriber (or willing/able to use a demo/pirated version of the CB).
