One thing to avoid is to have too many tags. The one by Merzedes is good - notice the lack of any 'saids', 'replied', answered, etc.
You don't need them a lot of the time.
The second thing is that if you're writing a LOOOONG scene with a lot of tags - saids, answereds, whatever - don't worry so much about using 'said'. It gets lost.
A lot of writers say NOT to use too many 'replied', 'whispered', 'growled', whatever. That should be evident much of the time in the actual speech. Too many very specific tags can be distracting. When you read a book, you tend to skim the 'she saids' and 'he saids'. They become placeholders, so long as they aren't overused. Have a look at a good, well-written book. There will likely be quite a few 'saids' that you overlooked the first time through.

But in a post, where it's probably going to be short, using varied tags probably isn't a bad thing. Or, like Merzedes points out, skipping on them altogether.
