It was announced today that BitTorrent has merged with (bought) µTorrent:

This is Bram Cohen, the creator of the BitTorrent protocol, and Ludvig (Ludde) Strigeus, the writer of µTorrent.

Together, we are pleased to announce that BitTorrent, Inc. and µTorrent AB have decided to join forces. BitTorrent has acquired µTorrent as it recognized the merits of µTorrent's exceptionally well-written codebase and robust user community. Bringing together µTorrent's efficient implementation and compelling UI with BitTorrent's expertise in networking protocols will significantly benefit the community with what we envision will be the best BitTorrent client.

In our opinion, µTorrent is the best BitTorrent client for Windows out there (including BitTorrent's own client, which isn't so great) so we see this as a very positive development for both parties involved.  We have been using µTorrent around here since v1.0 and it is certainly one of the finest pieces of free software ever written.  Congratulations on joining forces to both parties involved and we hope this leads to further development of one of the best new technologies of the 21st century.

mariposaHD would not be here without you!
