I wish I could tell you all of these neat things about Dave's Garden but I can't. You see Dave's Garden requires you to register and be a paid subscriber to view most of their forums and that doesn't sit well with me. I'm sure they do it to keep their operating costs down and from having their servers strained by every internet search. But if they were really that concerned they could stop having their forums indexed and be done with it. Instead they take advantage of all of the benefits of having a high page rank without giving people on the internet anything in return, unless you want to sign up and pay.
I'm sure the content on their forums is every bit as good as the content on GardenWeb but on GardenWeb you can get it for free! Anyone searching the internet for gardening related info can easily access it and join if they want unlike at Dave's Garden. Yes I know that it costs money to run a site but I don't think Dave's Garden is really all that desperate those ads you see on the site are there for a reason-to make money and it has a base of subscribers which also bring it money.
Don't even get me started on the look of the site and forum or the horribly placed advertising that non paying members see when they come to Dave's Garden from a search.
I give Dave's Garden ★ ★ out of 5 stars. One for the Garden Watchdog and one because I know a lot of people on GW who also post there. If you're looking for a gardening forum where you can read the threads before you sign up and that won't cost you money to join check the list on this blog for more references.
