Today was the day of unexpected releases. The first was Google Talk (as I noted before in this article) and now the same company released it’s popular Gmail to the general public.
I personally think that it was not planned, but the existing Gmail account is needed to use Google Talk, so they’ve made the decision to release Gmail (after 16 months of beta testing) to support the Google Talk.
Both services are free, but commercial and not as open as we want them. But they work so well, that they will be a must have in a few months.
