TextDrive (bought by Joyent) was one of the first hosting services to support Ruby On Rails as a first-class service -- in the days when static hosting, PHP, Perl, and Java/Tomcat were the only options on Linux infrastructure. They were well-noted for their "lifetime hosting" membership deal, which was incredibly exciting at the time (this was in a day where flat-fee and free hosting outside the likes of MySpace and Geocities was unheard-of). TextDrive was where all the cool kids hosted their projects.
RIP Joyent public cloud (and the last remnant of TextDrive's legacy).
Also I just remembered Strongspace (which was one of their products back then), very compelling and well designed online storage (e.g. for backup) back then. In a way this could have grown into Dropbox or Box when you think of it.
The Joyent email + calendar + notes web app was also quite impressive at the time. So many memories.
Strongspace still exists and is still hosting the VC storage accounts which Joyent shed (or at least, I think so... parts of their site seem to be dead).
ExpanDrive's "Cloud drive client software" is also well worth looking into.
They'll forever remain on my mind for their rip-off "lifetime hosting". I paid a lot of money for it, and it was supposed to last while the company lasted. But then they were folded into Joyent and the lifetime deals discontinued (with just a little bit limited time hosting offered in compensation).
I have stayed away from them forever since, and warned everybody I could about their terrible business practices.
RIP Joyent public cloud (and the last remnant of TextDrive's legacy).
