"I love Syntia". Duh.
"I have a Syntia feed". Double-duh.
[AsbjornUlsberg] I think it's an ok name. It doesn't make me jump around in joy, but it works.
[MartinAtkins] The fact that this isn't an already-existing English word makes me happy. On an off-topic note, I'm curious as to what the person who is camping on syntia.com had in mind when he or she registered it...
[AsbjornUlsbrg] A very good question. I have no clue, actually. Could be interesting to find out. All I found when searching for "Syntia" on Google, were some German women's webpages and some porno sites. Nothing we can't beat in Google PageRank.
[TomasJogin] Like "Sygnal" which possibly can be mistaken for "Signal" in spoken conversation, so can "Syntia" as "Cynthia". Personally, I think it's a non-issue though. See SygnalNameDiscuss for more on that.
[AsbjornUlsberg] I'm aware of the problem, but I don't think it's that big of an issue.
