Not all disks in the Google study were highly utilized 24/7. Arguably it might be better to turn a hard drive on and leave it on then to park & re-initialize the heads every day. A controlled data center environment is more likely to be beneficial to a hard drive than sitting on or under someone's desk getting knocked or collecting dust.
I am not doubting that SSDs are still experimental and have failures but the concept that HDD are way more reliable is overblown. Seagate has released many crap firmware updates or drives with bad firmware that tank the performance or brick the drive. Hitachi(previously IBM) was known for the "DeathStar" drive. Some manufacturers try to tell you to only run your drive 6 - 8 hours a day. Warranties are also shrinking.
Jeff Atwoods awesome for creating Stack Overflow, but I am not taking him as the end all be all SSD guru. Again, I could look through NewEgg reviews and give you 40 anecdotal cases of DOA disks or drives that just died. You could probably do the same for SSDs. A blog post has a terrible sample size.
