Those aren't logos -- that's just type with a series of second rate photoshop (or rather Gimp) filter effects. A logo actually communicates something about a brand -- a process that actually requires some thought, good taste and yes some talent. This would be like a graphic designer copying-and-pasting a Javascript file and then claiming to be a programmer.
What I had in mind was banners for websites, the image on the top with the name of the site, not brand logos.
While it may not always be the case (Aunt Betsy's Blog) in some cases the name of a blog may be a branded logo -- a good example of a bad example would be Techcrunch.
The name of the tool in Gimp is Alpha to LOGO. So, I can not wrong, it is the right word.
