When large groups of domain names are purchased such as the one I came across today, most of the time it indicates that the company purchasing them has major plans in the works.
That happened today, when I was alerted to the fact that Conde Nast Digital, the folks behind the popular Reddit website, purchased a few hundred domain names. These are not just ordinary Reddit domain names, they all include Reddit in the domain, and there are 285 of them. In my opinion, something interesting is going to be happening soon with the Reddit brand.
