I think not so off-topic too, as it very nicely shows that there are sellers here who know their jobs and that if you choose the right ones, you probably will have a great experience. I use WordPress myself and found the thread very interesting, plus I have an idea now where to go if I encounter problems I can’t solve myself.
The real problem as many similar forum discussions show, isn’t that there aren’t many skilled sellers here but seems to be that it’s not so easy for everyone to pick the right seller for them right away.
As is understandable, if you only got their (sometimes just copied) profile and gig descriptions to go by and especially if you don’t know enough to be able to tell from a brief inbox conversation if the seller knows their field, and, after all, you probably are looking for one because you aren’t that knowledgeable in that field in the first place.
Experience with Fiverr and the forum discussions certainly help to avoid pulling the bad luck card a second time, and as the moderators said a few times, there are a lot of people who don’t write but read, so I guess these kinds of discussions can be helpful not only to those taking part but to others as well.
I for one, am glad about the OT.
