Should we be muddying the relational waters? Use cases for MySQL & Mongodb | Scalable Startups

Seems I’m not the only one keeping away from JSON on the relational DB:

I would shy away from the NoSQL add-ons that some relational vendors have added, to compete with their newer database cousins. This starts to feel like a fashion contest after a while.

You can also get my point of view on this matter:

• JSON on MySQL: still not fond of it.
  
• JSON on the database? No thanks!
