I imagine this is as good a place as any to ask.
I've been with Bluehost for about two years. While their customer service is excellent (it really is), the amount of downtime is becoming unacceptable for a growing moderate-traffic (1,500-2,000 visitors/day) site.
I am also considering transitioning the site into multiuser (since 3.0 has that functionality built in, woohoo!) and Bluehost has informed me that they wouldn't be able to handle it if the site grew substantially.
SO . . .
Who would you recommend for hosting, especially but not exclusively for WPMU, and why? What's your experience been?
Cost is a concern, so scalability is important. Stability is also important.
Thanks for your advice and recommendations!
