What web hosting do you use?
carbocation: I started off with HostGator's shared service. I started going over their limits years ago (mostly CPU, IO, memory, and execution time). The execution time was a real kicker for me - they have reapers that go around looking for processes that have been running for more than 120 seconds, and kill them. So if you have a large MySQL database that you're trying to back up, good luck... At any rate, I'm not saying their policy was unreasonable - it was just a dealbreaker for me.At that point, I looked around for another host. I was impressed with MediaTemple's managed VPS offerings, as they had 3 levels of 'scaling' (for $50/100/150). Over the past 8 months, I've had major IO issues. Oddly, my IO issues have little correlation with my traffic patterns, so I suspect that I'm on a heavily loaded server - though they state that they see nothing but normal disk/CPU/etc utilization. That may be true, but I'm moving on.In the end, I decided that Linode offers a level of granularity that was not matched by MediaTemple. At Linode, they expect that you may well want to separate your production server from your MySQL server from your dev server, and their backend is built with multi-server management in mind. I've set up separate MySQL and PHP servers so far, and things have been going very well. This will allow me to scale each in proportion to its needs, instead of having to scale a monolithic server instance.For just a blog, do you want to mess around with the shell? If so, Linode or similar (SliceHost?) might be good for you. They start off small ($20/month for the cheapest), and they allow you to upgrade in small chunks.If you don't want to deal with shell, I find HostGator to be quite reasonable, and they are extremely cheap. I still host a bunch of personal sites with them.
