In my experience running https://thisaintnews.com the hardest part is getting and keeping users. It would probably be easier if I did some marketing, but that's too much like work! Still, it's not doing bad for something that's been around for 6 years, and hasn't been worked on in a year.
The second problem is motivation, after a certain amount of time, it becomes far less fun and much more of a burden, at which point you have to decide if you'll power through, give up, or quit totally.
The rest is just a software/hardware problem, and easily dealt with when needed.
As for the load, it's not that busy, but not that quiet for what it is, (http://stats.thisaintnews.com) and it runs on a cheap server from http://www.kimsufi.com/uk/, has a Xeon(R) CPU E3-1225 V2 @ 3.20GHz, 16Gb ram and 2x 1tb hdd, unlimited bandwidth and 1gbps link. It only costs about £25/month iirc.
