Waleed, I am not sure why you have issues, but I think it's wrong to say pubsubhubbub is unreliable. there may be issues, but they are only due to implementation issues... not to the protocol. It is hard to debug, but it can be done, and I believe this community has been helpful and have been able to fix issues often times.
Pankaj, I have offered help many times...
