I've been wanting to start another blog for what seems like forever and I'm finally going to take the plunge (really!). I was going to do this using multisite (with separate domains for each using the domain mapping plugin), but I was wondering if there were any disadvantages to doing this. I did some searching and came across a couple and was hoping that someone here might be able to address them. For instance:
If you ever want to switch web hosts, having separate installations makes the process easier. You may have an instance where one of the domains has become very popular and is using up a great deal of your hosting resources. In this case you would want to move that domain to it’s own account. If it is all wrapped up with all of your other domains within one WordPress installation it would be very difficult to separate it after the fact. (from here)
Is this true about switching hosts? I'm very happy with my host, but you never know what the future may bring. Would this really be an issue? And what about the popularity factor (I can dream) and having to separate a blog out?
Plugins can be an issue if they don’t support multisite. Every plugin is different, and you won’t know if it works until you try it (or someone comments on the plugin forum). A well written professional plugin shouldn’t be an issue, a simple small plugin should be ok as well. I have had issues with sitemap generators (well, it works just fine – but generates the wrong domain when using the domain mapping plugin... (from here)
Let me get this straight, if a plugin doesn't support multisite, then I can't use it at all? Would there be any workaround for this?
Are there any other disadvantages that don't have workarounds in multisite? Is there anything else I should consider when deciding between separate installations and multisite?
