My initial reaction was to agree with you, and certainly you have a good point about it possibly being more ethical to give money you don't need to charities.

But at the same time, Reddit is much closer to home for redditors. If I spend 30-60 minutes a day on Reddit, and like it, it has a very measurable impact on my life. It is in my own interest to keep it running. Whether it is a large corporation or not is beside the point. And by donating, I can become a "part" of the site, I can invest in its future (including upcoming premium features, if all goes well). In some sense, donating to Reddit is extremely capitalistic. Contrast with charity, which is non-capitalistic and much "better" in the sense of ultimate moral good, but where I'm never likely to see my $5 again or even hear how it was used.
