This isn't really about WPMUDEV, lets not target anyone else either, we're not a hit squad, this a generalised chit chat!
When using WordPress, plugins and themes this is what annoys me:
+ Public upgrade notices - WHY do my users need to know there is a new plugin version or that the next release of WordPress is here. It smells like Spamvertising to me! Its even worse when a plugin developer sticks several replicated bits of code all over rather than being a little OO or at least sticking it in a recycle bin (function for reuse). If you must use them then make sure it is only show to super admins.
+ Every theme that contains generator tags for WordPress! - Isn't it enough that spammers find your site through various means without sticking a big flashing beacon out inviting them to come piss on your community and business. And I don't need potential hackers/crackers knowing the version I use! Why make it easier for them!
+ Branding - I understand that designers and developers want to get their name whored out there, heck many of us have complex issues with life and require someway to claim some fame. But..... don't make it hard to remove those in your face spamvertising bits. If its commercial then why do it! The money is made and if its free then why not open a coffee tin for donations or charge a spam link removal fee.
+ I hate it when theme require separate plugins to make it work just like the demo!
So why this post?
Well perhaps it might help create some thought about these sort of things.
So what annoys you?
Remember play nice, because I know this sort of thread could turn....
