Guessing if a link leads to a weblog or not?

Technical weblog research question:

I have a list of links and I’d like to find out which of them lead to weblogs. Is there a way of doing this automatically?

Things that I thought about:

• guessing from url – would work for weblogs hosted in most popular platforms
• check if there is RSS/Atom feed – would exclude weblogs without feeds and include general sites with RSS feeds
• match url against database of any weblog indexing site – would include only subset of weblogs and you have to get the database first
• …

Do you have any suggestions?
