(I am addressing a specific one who knows who he is, but anyone else with similar inclinations should probably also read it):
It is generally a bad idea to contact bloggers by phone. My phone numbers are on my homepage so that my real-life friends and acquaintances don't have to search for them if they need them; they are not there because I would like to discuss my blog on the phone.
Not that I always mind discussing my blog verbally, but anything like that really should be either in the context of a larger blogger meet, or preceded by some kind of an earlier Net contact, and I mean a two-way one: you'd have to exchange some email with me, or hang out on the same forums, or be a regular commenter on my blog, or be someone whose blog I read. Remember that you know who I am, but I have no idea who you are.
It's not advisable to call total strangers at 22:30 on their home phone to discuss their views on multiculturalism. If you do, however, decide to do so, it would be quite polite to introduce yourself, and not to block my caller ID from seeing your number. "Suomalainen mies" is not a very useful answer to a request for an introduction: first of all, there are about 2.5 million of them, and then, I can sort of hear that you are a Finnish man from your voice and pronunciation.
You said, also in response to an introduction request, that you are shy. Me too, fairly shy with strangers. That's why I don't call them on the phone to have a chat about their political views.
If you don't feel ready to introduce yourself you should really consider not making the call.
There is another bad thing about anonymity: it awakens a hunting instinct in a person. If you had introduced yourself as Joe Shmoe and had a real phone number to go with it, I would most likely have not bothered checking; since you were all mysterious, I was quite curious. I'd rather not post any uniquely identifying details here, but AFAIK you are in Tampere, you are a first-time visitor to my blog, and you have searched it on a search term that was definitely not "multiculturalism".
In the unlikely event that I am wrong and you are in fact someone I would have recognized if you just introduced yourself, you are being very silly. I hardly ever eat people.
If you really do want to talk about multiculturalism in private and more or less anonymously, just take it to email. The address is on the beige strip near the top of the blog's front page. Again, I won't eat you, this post nonwithstanding.
